Question

Isabella uses the equation V = one-third (12) squared (9) pi to find the volume of the cone below.

Answer 1

Answer:

(D)Isabella should have divided the product of $12\pi \:cm^2$, and 9 by 3 to get $V=\frac{1}{3}*12\pi*9$.

Step-by-step explanation:

Isabella uses the expression: $V=\frac{1}{3}*12^2*9*\pi$ to find the volume of a cone with the following dimensions:

Height=9cm

Base Area =$12\pi \:cm^2$

Volume of a Cone ,$V=\frac{1}{3}*Base\:Area*Height=\frac{1}{3}\pi r^2 h$

$=\frac{1}{3}*12\pi*9$

Since the base area of the cone =$12\pi \:cm^2$, Isabella should have divided the product of $12\pi \:cm^2$, and 9 by 3 to get $V=\frac{1}{3}*12\pi*9$.
