Answer:

33.2 inches²

Step-by-step explanation:

Steps to derive the answer

  1. we are going to first determine the radius from the circumference
  2. we would calculate the area

Circumference of a circle = 2nr

n = 3.14

r = radius

20.41 = 2x 3.14 x r

Divide both sides by (2 x 3.14)

r = 3.25 inches

Area of a circle = nr²

3.14 x  3.25² = 33.2 inches²
