Answer:

351.658 square in

Step-by-step explanation:

First find the circumference of the circle

C = 25.13

Find area of the circle

A = 50.27

Multiply the circumference by the height

25.13 × 10 = 251.3

Add 251.3 with 50.27 twice

251.13 + 50.27 + 50.27 ≈ 351.658

Therefore your answer is D) 351.658 square in

Lana71 [14]

Answer:

He won 4 games
