Final answer:
The volume of a cylindrical fuel tank with a radius of 15 m and a length of 80 m is calculated using the formula V = πr²h, resulting in approximately 56,548.67 cubic meters.
Step-by-step explanation:
The volume of a cylindrical fuel tank can be calculated using the formula for the volume of a cylinder, which is V = πr²h, where V is the volume, r is the radius, and h is the height or length of the cylinder in this case. Given the radius is 15 m and the length (height) is 80 m, the volume of the fuel tank is calculated as follows:
V = π × (15 m)² × 80 m
V = 3.14159 × 225 m² × 80 m
V = 3.14159 × 18000 m³
V ≈ 56548.67 m³
Therefore, the volume of the fuel tank is approximately 56,548.67 cubic meters.
