S O L U T I O N :

According to the question,

  • Diameter of circle = 16 in

We are asked to calculate it’s circumference in terms of π.

Circumference of circle = 2πr

___________________________________

Let us first calculate the radius of the circle.

→ Diameter = 2 × Radius

→ 16 in = 2r

→ r = 16 in ÷ 2

→ r = 8 in

___________________________________

Substituting values in the formula of circumference,

→ C = 2πr

→ C = (2 × π × 8) in

C = 16π in

Therefore, 16π inches is the required answer.
