PLEASE HELP ME! Find the area of the circle with the given circumference C. Use 3.14 for π. Round to the nearest tenth after each step in your calculation.

C = 47.1 ft

The area of the circle is about ft2.

A = 176.6 ft^2

Step-by-step explanation:

We are given the circumference

C = 2*pi *r

47.1 =2*3.14*r

47.1 = 6.28 r

Divide each side by 6.28

47.1/6.28 =6.28r/6.28

7.5 =r

Now we need to find the area

A = pi r^2

A = 3.14 (7.5)^2

A = 176.625 ft^2

Rounding to the nearest tenth

A = 176.6 ft^2
