Question

the diameter of a cylinder is 7 yd. the height is 8 yd. find the volume and use pi and round to nearest 10th. V=__yd 3 little three^

Answer 1

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).
