Question

The volume of a cylinder with height and radius can be found using the formula

Suppose the volume of a cylinder is 1952 1 read the height is twice the radius what is the radius

of the cylinder. Determine the radius, rounded to the nearest whole foot

The radius is

feet

Answer 1

7 feet

Explanation:

Volume of a cyclinder = πr^2h

Volume of a cyclinder = 1952

π = 3.14

r = ?

h = 2r

Volume of a cyclinder = πr^2h

1952 = 3.14 * r^2 * 2r

1952 = 3.14 * 2r^3

1952 = 6.28r^3

Divide both sides by 6.28

r^3 = 1952 / 6.28

= 310.83

r^3 = 310.83

Find the cube root of both sides

r = 6.77 feet

Approximately 7 feet
