What’s the volume of this

Given:

The height of the cylinder = 12 in

The diameter of the base of the cylinder = 8 in.

To find:

The volume of the cylinder.

Solution:

The diameter of the base of the cylinder is 8 in. The radius is half of its diameter. So,

So, the radius of the base of the cylinder is 4 in.

The height of the cylinder, h = 12 in.

Base area of the cylinder is:

Where, B is the base area and r is the radius.

So, the base area is square inches.

The volume of the cylinder is:

Where, r is radius, h is height, B is base area.

Putting and , we get

So, the volume is cubic inches.

Therefore, .

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
