A cylinder gasoline can is 18 in across and 20 in tall which expression represents the approximate volume in cubic inches?

Answer 1

The expression that represents the approximate volume of the cylindrical gasoline can can be found using the formula for the volume of a cylinder:

Volume = π * radius^2 * height

The radius of the can is half of its diameter, so it is 18 in / 2 = 9 in.

Therefore, the volume is approximately equal to:

Volume = π * 9^2 * 20

Simplifying further:

Volume ≈ 3.14 * 81 * 20

Therefore, the expression that represents the approximate volume in cubic inches is:

Volume ≈ 5073.6 cubic inches.
