Question

The figure below shows two half-circles at the ends of a rectangle with the dimension shown.

Which is closest to the area of the figure in square inches?

A. 75
B.95
C.106
D.154

Answer 1

D. 154

Explanation:

The area of the rectangle is 15*5= 75 inches

The area of the 2 semicircles combined, which make a circle, are:

π*r², where r is 5

r²=25

π*25=78.53981633

75 + 78.53981633 is about 154
