Solution
The volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height.
Step 1: Find the radius. The diameter of the tank is 10ft, so the radius is half of that, which is 5ft.
Step 2: Substitute the values into the formula. V = π(5ft)²(7ft) = 3.14 * 25ft² * 7ft = 549.5 cubic feet.
Step 3: Round to the nearest whole number. The volume of the tank is approximately 550 cubic feet.
