Question

Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius.use 3.14 for pi and round your answer to the nearest hundredth.

Answer 1

Answer:

Volume of the cylinder = $254.34\,inches^3$

Step-by-step explanation:

Diameter of the cylinder = $6 \,inches$

Radius of the cylinder:

                 $\dfrac{6}{2} =3 \,inches$

Height :

              $3\times radius=3\times 3\\=9\,inches$

Volume of the Cylinder= $\pi \times r^2\times h$

$=3.14\times 3\times 3 \times 9\\\\=3.14\times 9 \times 9\\\\=3.14 \times 81\\\\=254.34\,inches^3$

The volume of the cylinder is: $254.34\,inches^3$
