Question

Answer:
A =
in?,
P =
in.

Answer 1

• See below

Explanation:

The area is the sum of areas:

• semicircle with r = 2 in
• semicircle with d = 2 in ⇒ r = 1 in

Find the area:

• A = πr² = π(2² + 1²) = 5π in² or 15.7 in²

The perimeter is the sum of:

• semicircle with r = 2 in
• semicircle with r = 1 in

Find the perimeter:

• P = 2πr = 2π(2 + 1) = 6π in or 18.8 in
