Find the volume of a spherical water tank that is 18 feet in diameter. Use 3.14 for pi. Round to the nearest hundredth.
What do you not understand about this? It's a matter of plugging in the numbers.
The volume of a sphere is (4/2)*pi*r^3.

To find the volume of a spherical water tank, you can use the formula:
V = (4/3) * π * r^3
where V represents the volume, π represents pi, and r represents the radius of the sphere.
In this case, the diameter of the water tank is given as 18 feet. To find the radius, divide the diameter by 2:
r = 18 ft / 2 = 9 ft
Now, you can calculate the volume using the formula:
V = (4/3) * 3.14 * (9 ft)^3
V ≈ (4/3) * 3.14 * 729 ft^3
V ≈ 3052.08 ft^3
Rounded to the nearest hundredth, the volume of the spherical water tank is approximately 3052.08 cubic feet.
