Question

The circumference of a circle is 11/pi inches. What is the area, in square inches, of the circle? Express your answer in terms of tt.​

Answer 1

A = 30.25·π^5

Explanation:

C = 2πr

11/π = 2πr

cross-multiply:

2π²r = 11

r = 11/2π² = 5.5π²

A = πr²

A = π(5.5π²)²

A = π(5.5²)π^4

A = 30.25·π^5
