Question

what is the area of the circle with circumference of 9.42 inches

Answer 1

@Heatherlynnlee You need to work backwards.

Answer 2

You need to find the radius, but that can be found by using the Circumferance formula.

Answer 3

C=2πr

Answer 4

My bad, C = 2(pi)r

Answer 5

So we're going to divide by pi(2), which is 6.28

Answer 6

9.42 / 6.28 = 1.48

Answer 7

Now we need to do 1.48 / 2 . Then we should get our radius.

Answer 8

7.065

Answer 9

9.42/3.14/2=1.5
1.5*1.5*3.14=7.065

Answer 10

Yep. Was my explaining correct?

Answer 11

It's a bit tricky as well, because it doesn't specify whether rounding is ~ tenth or ~ hundreth.
