Question

Find the diameter of a cylinder with a volume of approximately 2,307.9 mm and a height of 15 mm. Use 3.14 for pi.

Answer 1

Volume of a cylinder = pi * r^2 * h

Where:

pi: 3.14

r= radius

h= height

Replacing:

2,307.9 = 3.14*r^2*15

Solve for r:

2,307.9 / (3.14 *15) = r^2

49 = r^2

√49 = r

7= r
