Question

Jiro dispenses concentrated juice into cylindrical cans from a container that holds 2198 in3. The cans have a radius of 5 in. and a height of 7 in.
How many identical cans can Jiro fill?
Use 3.14 to approximate pi.

Answer 1

Find the volume of one cylindrical can.

V = pi * r^2 * h

V = 3.14 * 5^2 * 7

Simplify exponent:

V = 3.14 * 25 * 7

Multiply:

V = 549.5

Now divide this to the amount of juice that the large container holds.

2198 / 549.5 = 4

So Jiro can fill 4 identical cans.
