Question

PLEASE HELP 10 POINTS

Answer 1

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

Answer 2

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