Question

Find the circumference of a circle with a radius of 35 inches in terms of 7 and to the nearest tenth of an inch.​

Answer 1

Answer and Step-by-step explanation:

The circumference formula for a circle is:

C =
`2\pi r`

Plug 35 in for r (radius) and solve.

C =
`(35) 2\pi\\\\C = 70\pi\\\\C = 219.9`

So, approximately 219.9
`in^2` is the answer.
