Question

A right cylinder with a radius 4 cm and height 3 cm

Answer 1

V = B • h

V = (π • r • r) • h

V = (3.14 • 4 • 4) • 3

V = 150.72 cm^3

Answer 2

The volume of a cylinder is calculated as V = πr^2h.
r is the radius and h is the height.
If r = 4 and h = 3, then this formula would be V = π(4^2)(3).
π is about equal to 3.14, so we can use this in our formula as well.
(3.14)(4^2)(3)
Now we are ready to solve!

First, solve the exponent inside the parentheses.
4^2 = 16

(3.14)(16)(3)
Now just multiply each term from left to right.
3.14 • 16 = 50.24
50.24 • 3 = 150.72

So the volume of this cylinder is 150.72 cubic cm.

Hope this helps!
