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.

Answer 1

Answer:

length of the radius is 5cm

Step-by-step explanation:

Use formula for Volume of a cylinder to calculate radius;

Volume of a cylinder = $\pi r^{2} h$

$\pi$ = 3.14 (given)

Volume = 1,728$cm^{3}$

h = 22cm

r ; radius = ?

Plug in the numbers into the formula;

1,728 = 3.14 *$r^{2} *22$

1,728 = 69.08$r^{2}$

Divide both sides by 69.08 ;

1,728 / 69.08 = $r^{2}$

25.014476 = $r^{2}$

Find square root of both sides to solve for r;

$\sqrt{25.014476} =r$

r =5.0014

Therefore the approximate length of the radius is 5cm
