We can find the volume of the cylinder using the next equation:


V=\pi r^2h

Where h represents the height and r represents the radius.

The radius is the half value of the cylinder. Then :

r=d/2

r=7yd

r=3.5yd

Replacing:


\begin{gathered} V=\pi(3.5yd)^2(8yd) \\ V=98\pi yd^3 \end{gathered}

Hence, the volume is 98π yd³

98π yd³=307.9

The answer is decimal form is 307.9 ( The value is rounded to the nearest tenth).
