Question

What is the volume of a cylinder with a diameter of 12 in. and a height of 7 in.?

Answer 1

Answer

Find out the  volume of a cylinder .

To prove

Formula

$Volume\ of\ cylinder = \pi r^{2}h$

Where r is the radius and h is the height.

As given

Diameter of 12 in. and a height of 7 in.

$Radius = \frac{Diameter}{2}$

$Radius = \frac{12}{2}$

Radius = 6 in

$\pi = 3.14$

put all the values in the formula

$Volume\ of\ cylinder = 3.14\times 6\times 6\times 7$

                                          = 791.28 in³

Therefore the volume of the cylinder is 791 .28 in³ .
