Answer:
The volume of the gasoline in the tank is 18.85 cubic feet
Explanation:
The tank is a cylinder. The equation for calculating the cylinder volumen is πr²*h, r is radius and h is height. π is approximately 3.1416. So, The tank is resting horizontally on its side, its radius is 2 feet/2= 1 feet. h=a tank long= 6 feet.
With equation:
Vol gasoline=3.1416*1²*6=18.85 feet ³
I hope my answer helps you
