A cylindrical gasoline can is 18 inches across and 20 inches tall which expression Represent the approximate volume in cubic inches
The approximate volume of the cylindrical gasoline can can be calculated using the formula for the volume of a cylinder, which is given by:
Volume = π * r^2 * h
where π is a constant approximately equal to 3.14, r is the radius of the cylinder, and h is the height of the cylinder.
In this case, the can is 18 inches across, which means the diameter is 18 inches. The radius (r) of the cylinder can be calculated by dividing the diameter by 2:
r = 18 inches / 2 = 9 inches
The height (h) of the cylindrical gasoline can is given as 20 inches.
Plugging these values into the formula, the expression for the approximate volume in cubic inches is:
Volume = 3.14 * (9 inches)^2 * 20 inches
Simplifying this expression gives:
Volume ≈ 3.14 * 81 square inches * 20 inches
Volume ≈ 5073.6 cubic inches
Therefore, the approximate volume of the cylindrical gasoline can is 5073.6 cubic inches.
