What is the length of the diameter of a circle if the radius is 3.2 cm?
6.4cm since the radius of a circle is it's center point to any place on the side. A diameter is the straight line that comes from one point on the side passes through the center point and touches the other side Bottom Line: The diameter is double the radius.
Divide a circle into 12 equal parts?
Use a pair of compasses to draw a circle. Without changing the compasses, place the point of the compasses on the circumference and draw a small arc such that it intersects the circumference. Put the point on this intersection and repeat until you have 6 equally spaced "intersections". Select 2 adjacent intersections and, from each of them, draw an arc outside the circumference such that the 2 arcs intersect. Draw a line from this intersection to the centre of the circle. This line intersects the circumference halfway between the adjacent points. With the compasses set to the original radius of the circle (it's better to leave them fixed at this throughout!) place the compasses' point on the intersection of the straight line and the circumference then draw a series of arcs, as you did originally. These will complete the division by 12
How do you construct an angle of 90 degrees?
1. Draw a circle on a piece of paper.2. Draw a straight line from the top center line of the circle to the bottom center line.3. Draw a straight line from the left center line of the circle to the right center line.These lines should form a plus sign (+). Place your pencil point in the center of the circle where the two straight lines meet. Your pencil point is at the corner of four equal 90 degree angles.You can follow this method but it is inaccurate. A better way to construct a right angle is as follows:Draw a straight line using a rulerUse a pair of compasses to mark two arcs on the line that you have drawnPlace the compass point at the first point and adjust the compass so that the pencil goes just pass the point that you drew the first to linesDraw a major arc across the line with the line roughly in the centreRepeat for the second point, keeping the compass points the same distance apartJoin the two points where the arcs meetYou have bisected the line at the first point that you placed your compasses and have created four right angles.
Circle the digit in the tenths place 0.3?
0.3 is the same as 3/10 (three tenths)so the digit in the tenths place would be 3
Does always a tangent to a circle pass through the center of the circle?
the tangent will never go through the center of a cirlce. The tangent is, by definition, a line that only intersects the circle at one point. If you look down a pencil along its long axis, so that it appears to be a circle, and place your finger on top of and perpendicular to the pencil, your finger is now tangent to the circle you see.
What is a straight line that just touches a circle in one place called?
A straight line touching a circle is called a tangent. The following is the image of a tangent to a circle with center C and radius AC. The tangent touches the circle at only one point - A. visit our page: balajidentalhospital .com

What is the distance in a straight line from one place on a ripple to the same place on the next ripple?
The distance in a straight line from one place on a ripple to the same place on the next ripple is called the wave length.

How do you construct a equilateral triangle in a circle?
You will need... A set of compasses (for drawing the circle), and a straight edge. First, draw the circle. Then - put the point of the the compasses on the line. Mark the circle where the pencil crosses it. Place the point on this intersection and repeat the action until you're back at your starting point. Now - using the straight edge, join every alternate point to each other - forming an equilateral triangle.
What is a straight line about which rotation takes place?
Generally called an axis. Can also be pole.

Define the focus and the eccentricity of an ellipse?
A circle is perfectly round, and has one center. An ellipse is like a circle with TWO "centers", and each "center" is called a "focus". The plural of "focus" is "foci". Take a piece of string and tie a loop in each end. Put a pin through the loops, and hold it still in the center of the circle. Place the tip of your pencil at the center of the string, and you can draw a circle by keeping the string taut. Now take TWO pins, and put one pin at each end of the string; place the pins at some short distance apart, and hold them there. Place your pencil and draw, and the shape you draw will be an ellipse. The two pinpoints are the focuses, or foci, of the ellipse. Eccentricity is a measure of how far the ellipse varies from a circle. An ellipse with an eccentricity of zero _IS_ a circle, while an eccentricity of 1.0 is a straight line, with that string stretched out straight. In astronomy, every natural orbit is an ellipse.
What is a line that connects a point on a circle to the center of a circle?
The RADIUS. Other nomenclature for a circle are:- Diameter ; Two radii forming a straight line through the circle centre. Chord ; A straight line from one point on the circle to another point on the circle that does NOT pass through the circle centre. Arc ; Part of the circumference. Segment ; An area inside the circle bounded by two radii and an arc. Tangent ' A line just touching the circle's circumference in ONE place. NB The plural of the noun 'Radius' is 'RADII' , not radiuses. 'Radii' is pronounced 'Ray- dee - eye'. NNB 'pi' is the Classical Greek small case letter 'p' , for 'proportion. It is an Irrational number, but for elementary(school) purposes it is given as the approximation '3.14' or '22/7' Being an Irrational number means the decimals are NOT in any regular order and go to infinity. pi ~ 3.141592.....
