Question

A cone shaped cup has a radius of 4 inches and a height of 6 inches. Which measurement is the closest to the volume in cubic inches for the cup? Use 3.14 for π.
25.12 in³

12.28 in³

100.48 in³

6.14 in³

Answer 1

Volume of a cone can be found finding the area of the base of the cone, times the height of the cone, divided by 3. Or, V = $\frac{ \pi r^{2} h}{3}$

Substituting into the formula: V = $\frac{ \pi 4^{2} 6}{3}$ = 32(3.14) = 100.48
