A. 3 square inches
B. 153.48 square inches
C. 103.24 square inches
D. 253.96 square inches

Answer 1

I’m pretty sure it’s C

Answer 2

C.)

Explanation:

Add the area if the rectangle, to the area of the two semi-circles.

Area of Rectangle: L: 6
`(5)/(8)` in times W: 8 in = 53 in

Area of Semi-circle:
`(1)/(2)`(πr2):
`(1)/(2)`(π(4)2) = 25.13

(r is always half of diameter (d) so r=4)

53 + 25.13 + 25.13 = 103.26
