Question

What is the exact volume of a cylinder with a height of 8in and a diameter of 6 in

Answer 1

Answer:

$72\pi~in.^3$

Step-by-step explanation:

Use the formula for the volume of a cylinder:

$V = \pi r^2 h$

where r = radius of the base = diameter/2

h = height of the cylinder

$V = \pi r^2 h$

$V = \pi \left(\dfrac{6~in.}{2} \right)^2 \times 8 ~in.$

$V = 8~in\pi (3~in.)^2$

$V = 8~in.\pi (9~in.^2)$

$V = 72\pi~in.^3$

➷ You would use the formula:

volume = $\pi r^2*h$

Substitute in the values:

(note: the radius is half the diameter)

volume = $\pi (3)^2*8$

Solve:

Volume = 226.1946711

I'm not sure how far you require it rounded, or if you want the whole value so I will just leave the entire value. If you need assistance with rounding it to specific figures, just comment down below and I'll help.
