Question

Can someone please help me, I don’t understand this

Answer 1

113.04 square inches.

Explanation:

The formula to find the circumference is 2πr. The formula for the area is πr^2. We are trying to find r in order to solve the problem.

It says use 3.14 for π. The circumference is 37.68 inches.

2πr = 37.68

2 * 3.14r = 37.68

3.14r = 18.84

r = 6

Now that we know the radius of the circle, we can find the area!

πr^2 = 3.14 * (6^2) = 3.14 * 36 = 113.04.

Hope this helps!

Answer 2

To find the circumference

diameter x 3.14 = circumference

We can undo the multiplication and divide to get the diameter

37.68 /3.14 = 12

diameter / 2= radius

12 / 2 = 6

the radius is 6

radius x radius x pi = area

6 x 6 x 3.14 = 113.04

113.04 is the answer

Hope this helps
