Question

Circumference = 6 cm
3 cm
Find the volume

Answer 1

84.823 cm^3

Explanation:

V=πr2h=π·32·3≈84.823

Answer 2

V = 27 pi cm^3

Explanation:

To find the volume, we use the formula

V = pi r^2 h

Where r is the radius and h is the height

We know the circumference is given by

C = 2 pi r

6 pi = 2 * pi * r

Solving for r

3 = r

Going back to V

V = pi * (3) ^2 * 3

V = 27 pi cm^3
