FAN AND MEDAL!!

The formula for the circumference of a circle is C = 2πr, where r is the radius. Rearrange the formula to solve for r and select the correct option below.

r = C over 2 pi
r = 2πC
r = C − 2π
r = 2 pi over C,

Answer 1

Circumference of a circle, C = 2* pie * r Dividing through by 2 * pie; we have C/ 2 * pie = r r = C/ 2 * Pie * r The first answer r = C over 2 pie.
