How do you mark 72 a number hole in 1385 mm pitch circle diameter?
To mark the 72nd hole on a pitch circle diameter of 1385 mm, you need to first calculate the angular distance between each hole. The formula for this is 360 degrees divided by the number of holes. In this case, it would be 360 degrees divided by 72, which equals 5 degrees per hole. To mark the 72nd hole, you would measure 5 degrees from the starting point on the pitch circle diameter and make your mark.
How do you mark equidistant points on circle?
It is the radius from the centre to the circumference or the diameter passing through the centre to both sides of the circumference
How do you divide a circle into thirds?
Assuming you know the location of the center of the circle, to divide a circle into thirds, do the following:mark a point on the circumference and, using a protractor, mark 120 degreesthen repeat for the final markA line from the mark on the circumference to the center will show an angle of 120 degrees.
How do you find the perimeter of a flat shape?
"Flat shape" is a broad description that can be categorized into several more specific descriptions. For example, polygons, circles, and the outline of an irregular object such as a giraffe can all be described as flat shapes. For polygons, which are closed shapes with 3 or more straight sides, the perimeter is the sum of the lengths of the individual sides. The perimeter of a circle is pi (3.14) times the length of the diameter of the circle. A diameter is any line that connects two points on the edge of the circle and passes through the center. Other shapes have more specific perimeters, but in general, a flat shape's perimeter is the length of string that would be required to fully mark the outline of the shape.
How is diameter measured?
Let us assume you have a circle drawn with the center identified. Then draw one straight line through the center. Measure the length of the line bound by the intercepts of the straight line with the circumference of the circle. The line segment is the diameter. Another case would be that you have a circle drawn with no center marked. Draw one straight line through the circle. Use a compass to draw the perpendicular bisector of the line segment bound by the intercepts of the straight line with the circumference of the circle toward the inner circle (the center of a circle cannot lie outside the circle!). Repeat drawing another (different) straight line through the circle and finish with a perpendicular bisector. The two bisectors will intercept at the center of the circle. Then you can proceed the same way as described in the first paragraph above. Hint to draw a perpendicular bisector of a line segment: take one end of the compass, pivot the point at one end of the line segment and mark an arc with the other end on both sides of the line. Move the compass and pivot one point at the other end of the line segment. Mark an arc with the other end on both sides of the line. If the procedure is done correctly, the two arcs, one from each end, should intercept on one side of the line. There is another intercept of the two arcs on the side of the line. Connect the two arc-intercepts with a straight line. Convince yourself that the line bisects the straight line at a right angle. This last line is the perpendicular bisector of the original line (The first and last lines form the perpendicular bisector of one another). ===================

What is the radius of a circle with a diameter of 144?
72 The diameter is the full length from left to right and the radius is taken from a central point, in this cas at the 72 mark.
How do you divide a circle into 3 parts using only a confectionery ruler with no markings?
Draw a diameter on the circle from A to B and mark the midpoint, C (center of the circle). Mark the midpoint, D, of one of those radii (halfway between center and edge). Draw a perpendicular line to the diameter from D to the two edges of the circle, E and F. Draw radii from E to C and F to C. Lines AC, EC, and FC mark the three equal parts of a circle.
You want to drill three equadistant holes in a circle three inches in diameter?
simple option: take a string, wrap it around the tube, cut off extra, measure the string. Divide by 3, use a ruler to mark the 3 spots on the string, wrap back around tube, and transfer the dots to the tube. DRILL! Accurate option: find circumference of tube. (you can find this by measuring the diameter of the tube, multiply that by PI) divide by 3, mark a starting point, drill holes offset by your length.
How do you mark equidistant points on circle?
It is the radius from the centre to the circumference or the diameter passing through the centre to both sides of the circumference
How do you divide a circle with 9cm diameter in three equal parts?
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
If the diameter of the circle is 60 what is the radius?
The radius of a circle is always half of the diameter. Therefore, if the diameter of the circle is 60 units, the radius would be half of 60, which is 30 units. The formula to calculate the radius from the diameter is: radius = diameter / 2. In this case, the radius would be 30 units.
How big is the semi circle on a football pitch?
The center circle is 10 yards in radius. The penalty arc is 10 yards from the penalty mark. The corner arcs are all 1 yard from their corresponding corner. A semi-circle is exactly one half of a circle and there aren't any on the a football pitch.
What is R in a circle called?
the "r" in a circle is called "Radius". It the same as half of the diameter. ---- A capital R in a circle is a registration mark. It is used to signify registration of a trademark and is placed on a product to signify ownership of the rights to that product.
How do you draw a diagram that shows what pi means?
-- Draw a circle. -- Put a mark at the center, and draw a line across the whole circle through the center. -- Measure the length of the curved line all around the circle. (called the "circumference" of the circle) -- Measure the length of the straight line across the circle. (called the "diameter" of the circle) If you divide the circumference by the diameter, the result is 'pi'. It doesn't matter how big or how small the circle is. The result is always the same.
What is the birthday of mark holes of platinum blonde?
JULY 29, 1961, His name is Mark Holmes not Mark Holes
Mark has a piece of string 12 inches long he shapes string into rectangle that encloses an area of 5 square inches Can Mark enclose a greater area with the same string If sowhat is the area?
If Mark makes a circle, that circle would have a circumference of 12 inches. The formula for circumference is pi times diameter, so the circumference divided by pi will give you the diameter of 3.82 inches. Divide this by 2 to get the radius of 1.91 inches. Area of a circle is pi times the radius squared. 1.91 squared is 3.6481. Multiply this by pi to get 11.46 square inches of area inside the circle. A circle is always the most efficient use of space possible given a fixed perimeter. If Mark makes a square with equal sides where all sides are 3 inches, the area would be 9 square inches. 3 X 3 = 9
