Answer:

Explanation:

We are given the circumference. The formula for circumference is

C = πd where d is the diameter and C is the circumference.

We are given C = 53.41, so we have...

53.41 = πd

Solving for d gives us...

53.41/π = d

The formula for area of a circle is

A = π(r²) where A is the area, and r is the radius

The radius is half of the diameter, so we divide 'd' by 2 to get the radius...

r = d/2 = (53.41/π)/2 = 26.705/π

The area of the circle is...

A = π(26.705/π)²

A = π(26.705²/π²)

A = 26.705²/π

A = 227.0049315 in²
