Question

The cone has a circular base with a diameter of 8 feet and a height of 5.-8 feetFP15 feetWhat is the volume of the cone?83.8 cubic feet251.2 cubic feet314 cubic feet628 cubic feet

Answer 1

Answer:

83.8 cubic feet

Explanation:

The volume of a cone can be found using the below formula;

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

where pi = 3.14

r = radius of the base = diameter/2 = 8/2 = 4 feet

h = height of the cone = 5 feet.

Let's go ahead and substitute the above values into our formula and solve for V;

$\begin{gathered} V=3.14\times4^2\times\frac{5}{3} \\ V=3.14\times16\times\frac{5}{3} \\ V=83.8ft^3 \end{gathered}$
