How do draw a line to show the diameter of a circle?
Draw a straight line that bisects the circle and passes through the center.
How do you draw a diameter of circle?
Construct a circle with a compass and then draw a straight line through its centre
Does the diameter divide the circle into fourths?
A diameter is a line connecting any two points in a circle that passes through the centre of a circle. You can draw 1 diameter and divide the circle in half. You can draw 2 and divide it into 4 pieces or draw an infinite amount and divide it into infinite pieces.
How do you find tha radius?
The radius is half the diameter. Draw a line that passes through the centre of the circle and measure it. This is the diameter. Halve it and you will have the radius.
What is the definition of radius and diameter?
If you draw a line from one side of a circle to the other, and that line hits the center, and goes all the way across, it is the diameter. half of that line going from the center to the edge of the circle is the radius.

How do you make an equal lateral triangles in a circle?
draw the diameter draw a line making a 30 degrees angle from one side of the diameter draw another one making a 30 degrees angle from the other side of the diameter join the points where these two lines intersect the circle.

What is a radiu s of a circle?
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
How is a diameter worked out?
A circle has an infinite number if diameters, but they are all the same length. The length of the diameter of a circle is the length of the longest straight line that can be drawn completely inside the circle. If the center of the circle is marked, then it's easy to draw a line that is a diameter ... it's any line that passes through the center of the circle.
How do you make the r in a circle?
The 'r' means the radius, exactly half of the diameter. Find the centrepoint of the circle, then draw a line from the centre to the outside. This line is your radius.
How do you find a chord of a circle with diameter 26?
There are an infinite number of possible chords in anycircle, regardless of its diameter. A chord is a line segment with its endpoints on the curve (circumference) of the circle. You can draw those all day and never draw the same one twice.
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.
How to calculate how big of circle could be made with length of a line?
IF YOU HAVE A LINE THAT WILL GO AROUND THE CIRCLE, DIVIDING BY PI (3.14159) WILL GIVE YOU THE DIAMETER. HALF THE DIAMETER IS THE RADIUS. IF YOU HAVE A LINE FOR DIAMETER, MULTIPLY BY PI TO GIVE THE CIRCUMFERENCE. TO DRAW THE CIRCLE, FOLD THE LINE IN HALF AND HOLD AT THE FOLD. EITHER OR BOTH OF THE ENDS WILL SWING AROUND THE CIRCLE. IF YOU USE YOUR LINE FOR THE RADIUS, MULTIPLY THE LENGTH BY 2, THEN MULTIPLY THAT RESULT BY PI. RADIUS IS 1/2 THE DIAMETER (1/2 THE DISTANCE ACROSS) DIAMETER IS THE DISTANCE ACROSS CIRCUMFERENCE IS ALL THE WAY AROUND IF YOU HAVE A LINE THAT WILL GO AROUND THE CIRCLE, DIVIDING BY PI (3.14159) WILL GIVE YOU THE DIAMETER. HALF THE DIAMETER IS THE RADIUS. IF YOU HAVE A LINE FOR DIAMETER, MULTIPLY BY PI TO GIVE THE CIRCUMFERENCE. TO DRAW THE CIRCLE, FOLD THE LINE IN HALF AND HOLD AT THE FOLD.
