Question

PLEASE HELP 10 POINTS

Answer 1

The exact radius of a circle with a radius of 12 inches is 75.4. The formula is 2πr.

Answer 2

we are given

`radius=r=12inches`

we have to find circumference

so, we can use formula

`C=2\pi r`

where

r is radius

C is circumference

we are given

r=12

so, we can plug here

`C=2\pi *12`

`C=24\pi`

Since, it is asking for exact circumference

it means it should be without any decimal

so,

`Circumference =24\pi inches`............Answer
