Answer 1

`\Huge\boxed{131.88}`

Explanation:

Hello There!

First thing we want to do is find the formula for circumference of a circle

C = 2(3.14)r

where r = radius

we are given the diameter so we have to convert that into radius to do so we just divide by 2

42/2=21 so the radius equals 21 inches

now we just plug in 21 for r in the formula

`C = 2(3.14)21\\2*3.14=6.28\\6.28*21=131.88\\C=131.88`

So we can conclude that the circumference of the circle is 131.88 inches
