Question

John has a cylindrical water tank in his house with a 4 m radius and 15 m height. The cost of filling the water in the tank is $0.5 per cubic meter. What would be the cost of filling the complete tank? (Use pi = 3.14)

Answer 1

$377

Explanation:

Volume of a cylinder is;

V = πr²h

Where;

r is radius

h is height

We are given;

radius; r = 4 m

Height; h = 15 m

Thus;

V = π × 4² × 15

V = 753.9822 m³

Cost of filling the tank is $0.5 per m³.

Thus, total cost to fill this tank is;

C = 0.5 × 753.9822

C = 376.9911

C ≈ $377
