Question

Find the volume of the conical paper cup.

(Radius 3 cm)

(Height 8 cm)


A. 24 cm

O B. 72 7 cm3

C. 64 7 cm3

D. 8 TT cm3

Answer 1

`\textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=3\\ h=8 \end{cases}\implies V=\cfrac{\pi (3)^2(8)}{3}\implies V=24\pi ~cm^3`
