Question

The circumference of a circle is 22π in. What is the area, in square inches? Express your answer in terms of \piπ.

Answer 1

Answer:

A = 121π in²

Step-by-step explanation:

The circumference (C) of a circle is

C = 2πr ( r is the radius )

Here C = 22π , that is

2πr = 22π ( divide both sides by 2π )

r = $\frac{22\pi }{2\pi }$ = 11

The area (A) of a circle is

A = πr² = π × 11² = 121π in²
