What is the volume of a right circular cylinder with a base diameter of 18yd. And a height of 3yd.

saveliy_v [14]

Answer:

$Volume=254$ to the nearest cubic yard.

Step-by-step explanation:

The volume of a right circular cylinder can be calculated using the formula;

$Volume=\pi r^2h$ .

The diameter of the base is given to us. We divide it into two to obtain the radius.

$r=\frac{18}{2}=9yd$ and also the height of the cylinder is $h=3yd$ .

We substitute these values into the formula to obtain;

$Volume=9^2\times 3\pi yd^3$

$Volume=243\pi yd^3$

$Volume=763.4yd^3$
