homework 2
vol
find the volume of each cone to the nec
1.
r = 7
2.

Explanation:

Step1: Recall cone volume formula

The volume $V$ of a cone is $V = \frac{1}{3}\pi r^2 h$

Step2: Substitute given values

Substitute $r=7$, $h=14$:
$V = \frac{1}{3} \times \pi \times 7^2 \times 14$

Step3: Calculate numerical value

First compute $7^2=49$, then $49 \times 14=686$:
$V = \frac{686}{3}\pi \approx \frac{686}{3} \times 3.1416 \approx 718.38$

Answer:

$\approx 718.4$ (rounded to the nearest tenth)
