Solve the problem. Use 3.14 as the approximate value of $\pi$. Round to the nearest tenth unless instructed otherwise.
-A certain marine engine has cylinders that are 4.64 inches in diameter and 5.17 inches deep. Find the total volume of 6 cylinders.
A) 524.3 inches $^{3}$
B) 87.4 inches $^{3}$
C) 1048.5 inches $^{3}$
D) 903.9 inches $^{3}$

Question

Quizplus · Accepted Answer

The volume of one cylinder is calculated using the formula $V = \pi r^2 h$, where $r$ is the radius and $h$ is the height (or depth) of the cylinder. Given the diameter is 4.64 inches, the radius is half of that, which is 2.32 inches. The depth is 5.17 inches. Thus, the volume of one cylinder is $V = 3.14 \times (2.32)^2 \times 5.17$. Calculating this gives approximately 87.4 inches$^3$ for one cylinder. For 6 cylinders, multiply by 6: $87.4 \times 6 = 524.4$ inches$^3$, which rounds to 524.3 inches$^3$, matching option A.
