Question

The diameter is a circle is 16cm. Find it’s circumference in terms of π.

C= ________cm

Answer 1

Circumference of the circle = 100.53 in.

Explanation:

Circumference of a circle is given by the formula,

Circumference = 2πr

Radius of the circle 'r' = 16 in.

Therefore, circumference of the circle with radius 16 in will be,

C = 2π(16)

C = 32π

C = 100.53 in.
