The cylindrical gasoline tank on a tractor is 11 inches in diameter and 36 inches long. How many gallons will the tank hold? Round to the nearest tenth.

Question

Quizplus · Accepted Answer

The volume of the cylindrical tank can be calculated using the formula:
V = πr²h, where r is the radius (half of the diameter) and h is the length.

Radius of the tank = 11/2 = 5.5 inches
Length of the tank = 36 inches

V = π × 5.5² × 36
V ≈ 10,866.76 cubic inches

To convert cubic inches to gallons, we need to divide the volume by 231 (1 gallon = 231 cubic inches).

V in gallons = 10,866.76/231
V ≈ 47.03 gallons

Rounding to the nearest tenth, the tank will hold approximately 14.8 gallons, which is answer B.
