Question 9 • Mathematical Models with Applications - MA4072 CR

A funnel is shaped approximately like a cone. The diameter of the base is 6 inches. The height is 10 inches. What is the approximate volume of the funnel? Use 3.14 for pi, and round to the nearest tenth.

Answer
A
94.2 in.3
B
18.8 in.3
C
226.1 in.3
D
28.3 in.3

Explanation

The cone’s radius is half its 6-inch diameter, so r = 3 inches. Use V = (1/3)πr²h: (1/3)(3.14)(3²)(10) = 94.2 cubic inches. The best answer is 94.2 in.³.
