Question

Find the volume of a cylinder that has a diameter of 6 and a height of 9

Answer 1

$v = \pi \times {r}^{2} \times h$

where r is radius and h is height.

diameter is 6 so the radius is 3. because 2 times the radius is called a diameter.

and the height is 9.

$v = \pi \times {3}^{2} \times 9$

and the answer is 254.47 cm cubed
