Question

a bricklayer uses a cylinder to store sand. the cylinder is 5ft. tall and has a radius of 0.5 ft. Each batch of mortar contains 0.48 ft. of sand. How many batches of mortar can the bricklayer make with one cylinder of sand? Express your answer as a whole number.

Answer 1

Volume of a Cylinder:

V = pi * r^2 * h

Plug in what we know:

V = 3.14 * 0.5^2 * 5

V = 3.925

Now we divide 3.925 / 0.48 to find out how many batches of mortar we can make with one cylinder of sand.

3.925 / 0.48 = 8

So he can make 8 batches of mortar.
