The diameter of a cylindrical water tank is 8ft, and its height is 10ft. What is the volume of the tank?
To find the volume of a cylindrical tank, we use the formula V = πr^2h, where r is the radius and h is the height.
Given that the diameter of the tank is 8ft, we can find the radius by dividing the diameter by 2:
Radius (r) = 8ft / 2 = 4ft
Now we can plug in the values into the formula:
V = π(4ft)^2 * 10ft
V = π(16ft^2) * 10ft
V = 160π ft^3
Using the approximate value of π as 3.14, we have:
V ≈ 160 * 3.14
V ≈ 502.4 ft^3
Therefore, the volume of the cylindrical water tank is approximately 502.4 cubic feet.
