The volume of a cylinder is 525 cm3. The radius of the base of the cylinder is 5 cm. What is the height of the cylinder? The hei
elena-14-01-66 [18.8K]

you do not give a value for PI so I am using 3.14

V=PI x r^2 x H

you know volume and radius so put those into the equation

525 = PI (3.14) x 5^2 x H

525 = 3.14 x 25 x H

525 = 78.5 x H

divide both sides by 78.5

6.687 = H

round off answer as needed 6.7cm or 6.69cm

 NOTE : the answer may vary slightly depending on the value of PI used.

 but this is how you calculate the height.
