Find the volume of a right circular cone that has a height of 9.1 m and a base with a circumference of 12.1 m. Round your answer

Orlov [11]

Answer:

$V=35.3\ m^3$

Step-by-step explanation:

-Given the cone's height is 9.1m and the Circumference is 12.1

#We use the circumference formula to calculate the radius:

$C=2\pi r\\\\12.1=2\pi r\\\\r=\frac{12.1}{2\pi}=\frac{6.05}{\pi}\ cm$

-The volume of the cone using the radius above can then be calculated as follows:

$V=\pi r^2\frac{h}{3}\\\\=\pi\times(\frac{6.05}{\pi})^2\times \frac{9.1}{3}\\\\\\=35.3\ m^3$

Hence, the cone's volume is $35.3\ m^3$
