Question

find the volume of the right cone below. round your answer to the nearest tenth if necessary.

Explanation:

Step1: Find the radius

The diameter \(d = 18\), so the radius \(r=\frac{d}{2}=\frac{18}{2}=9\).

Step2: Use the volume formula for a cone

The volume formula for a cone is \(V=\frac{1}{3}\pi r^{2}h\). Substitute \(r = 9\) and \(h=25\) into the formula:

$$

$$

Step3: Calculate the numerical value

\(V=675\pi\approx675\times3.14 = 2119.5\)

Answer:

\(2119.5\)
