Find formulas for the circle's radius, diameter, circumference and area , in terms of 'a'. As we've shown above, the circle's radius is equal to the half the length of the square's side, so r=a/2. The diameter is twice the radius, so d=a. The circumference is d ·π, so C=πa. WebAnd in this kind of figure, we have a couple of circles, one having radius R and other having radius as r.
