Answer:

A = 78.54 in^2

Explanation:

Circumference of the circle = 10 pie inches

Determine the area of the circle.

Formula for the area of the circle:

A = pi r^2

Formula for the circumference of the circle:

C = 2 pi r

Solution:

Solve first for the radius of the circle by using the circumference of the circle.

10 pi in= 2 pi r

Divide 2 pi on both sides of the equation in order to determine the value of r.

10 pi in/2 pi = 2 pi r/ 2 pi

r = 5 inches

Substitute the value of r to the formula for the area.

A = pi (5 inches)^2

A = 25 pi in^2

A = 78.54 in^2

Final answer :A = 78.54 in^2

I hope I helped
