Amanda makes colored paper cone cups to serve nuts at a charity event. The height of each paper cone is 15 centimeters, and the

allsm [11]

Answer:

$V=261.80 \ cm^3$

Step-by-step explanation:

-The volume of a cone is given by the formula:

$V=\pi r^2 \frac{h}{3}$

Where:

r is the cone's radius.
h is the cone's height.

#We substitute for r and h in the formula to solve for V:

$V=\pi r^2 \frac{h}{3}\\\\=\frac{1}{3}\pi \times 5^2\times 10\\\\=261.80\ cm^3$

Hence, the each cone's volume is $261.80 \ cm^3$
