How big is a 90mm circle?

The diameter of the circle is 9 centimeters. You can yourself construct this circle by taking 4.5 cms on your rounder and drawing a circle. The resultant circle will be a 90mm circle. Then you'll see how big it is.


How do you find the volume of a circle?

A circle has no volume. It is a planar figure and is flat, and it has no thickness. A circle does not have any thinkness just as a plane, the construct on which it is drawn, has no thickness.

Can you cut a circle into 5 equal parts?

AnswerThere are 2pi radians in a full circle. If we cut a circle into 5 equal parts, each central angle will have 2pi/5 (or 72 degrees), and each arc intercepted form those central angles will be (2/5)(pi)(r). AnswerYes, you can, using just a compass and straight edge. For any given circle you construct, construct a pentagon inside it using that compass and straight edge, then use the vertices of the pentagon to divide the circle into 5 equal sectors. Use the link below to see how the construction proceeds.
