There are 12 cylindrical cans in a package. Each can has a height of 4.9 in. and a diameter of 2.5 in. What is the approximate total volume of the 12 cans?

Answer 1

The volume of a cylinder can be calculated by using the formula V = πr^2h, where V is the volume, r is the radius, and h is the height.

First, we need to find the radius of each can. The diameter is given as 2.5 inches, so the radius is half of that or 1.25 inches.

So, the volume of one can is:

V = π(1.25 in)^2(4.9 in) ≈ 24.12 cubic inches

To find the total volume of 12 cans, we can simply multiply the volume of one can by 12:

Total volume = 12 cans × 24.12 cubic inches/can ≈ 289.44 cubic inches

Therefore, the approximate total volume of the 12 cans is 289.44 cubic inches
