ASAP ILL GIVE BRAINLIEST IF UR RIGHT!!! The radius of the cone is 5 in and y = 13 in. What is the volume of the cone in terms of

Blababa [14]

Answer: V = $100\pi$ $in^{3}$ (third option)

Given Information:

V = $\frac{1}{3}\pi r^{2} h$ <-- volume formula.
r = 5
y = 13
<em>h = ?</em>

To find h...

h, r, and y make a right triangle.
h and r are the two legs, y is the hyptenuse.
$h^{2} + r^{2} = y^{2}$
$h^{2} + 5^{2} = 13^{2}$
$h^{2} + 25 = 169$
$h^{2} = 144$
h = 12

Use formula:

V = $\frac{1}{3}\pi r^{2} h$
V = $\frac{1}{3} \pi (5)^{2} (12)$
V = $\frac{1}{3} \pi (25)(12)$
V = $\frac{1}{3} \pi (300)$
V = $100\pi$
