Dividig circle into 18 equal parts?
A circle has 360 degrees. Divide 360 by 18 and you will find that each equal part of the divided circle is 20 degrees.
What is the radius of a circle with a circumference of 20 pi?
Divide the circumference by (2 x pi).
If the Circumference of a circle is 20 what is its radius?
Just divide the circumference by (2 x pi). Pi is about 3.1416.
Area of an arch of circle with a radius of 70 feet The angle of the arch is 20 degrees?
855.21 square feet. A circle with a radius 70 would be (pi)(radius squared) = (3.1416) (70) (70) = 15,393.8 square feet. With a 20 degree angle that is 20/360ths of a circle, so multiply your circle area by 20 and divide by 360 = 855.21 square feet.
What is the diameter of a circle that is 20 inches long?
The diameter is the same as the length, so it is 20 inches. If you meant to say that the circumference was 20 inches, then divide by pi, which is 3.1416 20 / 3.1416 = 6.4 inches

How do you divide a 20 diameter circle into 9 equal segments?
Forget the diameter. Find the centre. Draw any radius. Next, add another radius at 360/9 = 40 degrees to the first. Keep adding radii as you go around the circle. When it is in 9 equal slices you will have returned to the first radius. Done.
