Question

What is the approximate volume of a cone with a height of 12 in. and radius of 9 in.?

Answer 1

The formula for calculating the cone volume is: 
$V = \frac{ \pi *r^2* h}{3}$

Data:
h (height) = 12 in
r (radius) = 9 in
Use: $\pi \approx 3.14$

Solving:
$V = \frac{ \pi *r^2* h}{3}$
$V = \frac{ 3.14 *9^2* 12}{3}$
$V = \frac{ 3.14 *81* 12}{3}$
$V = \frac{3,052.08}{3}$
$V = 1,017.36 \to \boxed{\boxed{V = 1,017.4\:in^3}}\end{array}}\qquad\quad\checkmark$

Answer 2

the answer is actually 1017.36 ! i took the test and did 1017.4 and it said it was wrong
