Question

What is the circumference of a pizza that has a radius of 6 inches?

Answer 1

Applying circumference formula,

2*pi*r

plug in

2*pi*6

around 37.7

Answer 2

radius of pizza(r) = 6 inches

circumference of pizza(C) = 2 π r

=> C = 2 π × 6

=> C = 12 π inches

or C = 12 × 22/7 = 264/7 inches
