Calculate the height of 385cm of water
inside a cylinder of diameter 7cm.

C

Step-by-step explanation:

The volume formula for a cylinder is A = πr²h where A, r, and h are area, radius, and height respectively. The radius is 1/2 the diameter which is 7 / 2 = 3.5. We are solving for h so we can write:

385 = 22/7 * (3.5)² * h

385 = 38.5 * h

h = 10
