volume of cylinders - item 20987 question 1 of 7
you have a can that is in the shape of a cylinder. it has a volume of about 1,728 cubic centimeters. the height of the can is 22 centimeters. what is the approximate length of the radius? use 3.14 for pi.

length of the radius is 5cm

Step-by-step explanation:

Use formula for Volume of a cylinder to calculate radius;

Volume of a cylinder =

= 3.14 (given)

Volume = 1,728

h = 22cm

r ; radius = ?

Plug in the numbers into the formula;

1,728 = 3.14 *

1,728 = 69.08

Divide both sides by 69.08 ;

1,728 / 69.08 =

25.014476 =

Find square root of both sides to solve for r;

r =5.0014

Therefore the approximate length of the radius is 5cm
