Corrected Question

One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder. If the first cylinder’s volume is 216cm³, what is the correct equation and value of x, the volume of the second cylinder?

Answer:

The equation is:
216=(7)/(8)x-8

Volume of the second cylinder=
256cm^3

Explanation:

Volume of the first cylinder=
216cm^3

Let the volume of the second cylinder=x

7/8 of the volume of a second cylinder=
(7)/(8)x

8 less than 7/8 of the volume of a second cylinder=
(7)/(8)x-8

Therefore, the equation is:


216=(7)/(8)x-8

Next, we solve for x


216=(7)/(8)x-8\\216+8=(7)/(8)x\\224=(7)/(8)x\\$Cross multiply\\7x=224*8\\Divide both sides by 7\\x=256cm^3

The volume of the second cylinder is
256cm^3
