Well, sweetheart, to divide a circle into 20 equal parts, you simply start by drawing a vertical line through the center, then draw another line at 18 degrees from the first line, and keep going at 18-degree intervals until you've got yourself 20 equal slices of that circle. Easy as pie... or should I say, easy as circle?

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
