Question

What is the circumference of the circle with radius 8cm in terms of ?

A: 16cm B:4cm C:64cm D:32cm

Answer 1

Explanation:

`C = 2\pi *r\\r = 8cm\\C = 2*\pi*8\\C = 16 \pi cm`

Answer 2

C =
`16\pi cm`

Explanation:

Circumference of circle =
`2\pi r`

Where Radius = 8 cm

C =
`2(\pi )(8)`

C =
`16\pi cm`
