A) 942.0 in $^{3}$
B) $471.0 \mathrm{in}^{3}$
C) 235.5 in $^{3}$
D) 376.8 in $^{3}$

Question

Quizplus · Accepted Answer

The volume of a cylinder is given by the formula $ V = \pi r^2 h $. The radius $ r $ is half of the diameter, so $ r = 2.5 $ inches. The height $ h $ is 12 inches. Thus, the volume is $ V = 3.14 \times (2.5)^2 \times 12 \approx 235.5 $ cubic inches.
