Question

find the volume of the cone. use 3.14 for pi and round your answer to the nearest tenth.
22 ft
22 ft

a. 506.6 ft³
b. 5,267.2 ft³
c. 11,144.9 ft³
d. 2,786.2 ft³

Explanation:

Answer:

The volume formula for a cone is \(V=\frac{1}{3}\pi r^{2}h\). Here \(r = \frac{22}{2}=11\) ft and \(h = 22\) ft. Substituting \(\pi = 3.14\) into the formula: \(V=\frac{1}{3}\times3.14\times11^{2}\times22=\frac{1}{3}\times3.14\times121\times22=\frac{1}{3}\times3.14\times2662\approx2786.2\) ft³. So the answer is d. 2,786.2 ft³
