Question

what is the volume of this sphere? round your answer to the nearest hundredth. 18 ft cubic feet

Explanation:

Step1: Find the radius

The diameter is 18 ft, so the radius $r=\frac{18}{2}=9$ ft.

Step2: Use the volume formula

The volume formula for a sphere is $V = \frac{4}{3}\pi r^{3}$. Substitute $r = 9$ into the formula: $V=\frac{4}{3}\pi(9)^{3}$.

Step3: Calculate the volume

$V=\frac{4}{3}\pi\times729 = 972\pi$. Using $\pi\approx3.14159$, $V\approx972\times3.14159 = 3053.63$.

Answer:

$3053.63$
