The diameter of the cylinder given = 3 yd.
the height given = 4 yd.
The radius is half of the diameter. So, the radius of the cylinder = (3/2)yd.
The formula to find the volume of the cylinder =

Where, r = radius, and h = height.
Now we can find the volume by plugging in the values of r and h in the formula.
The required volume of the cylinder
=

=

=

=

=

Volume of the cylinder =
= 27.3 yd³
