whats the volume of a sphere with diameter 30ft with the answer in the terms of pie?

radius = 15 ft

Vol = (4/3)π(r^3)
= (4/3)(π)(15^3)
= 4500π

To find the volume of a sphere, you can use the formula V = (4/3) * π * r^3, where V is the volume and r is the radius of the sphere.

In this case, you are given the diameter of the sphere, which is 30 feet. The radius, r, can be calculated by dividing the diameter by 2: r = 30 ft / 2 = 15 ft.

Now, substitute the radius into the formula:
V = (4/3) * π * (15 ft)^3

To calculate the volume, you need the value of π, which is a mathematical constant approximately equal to 3.14159.

So, plug in the values:
V = (4/3) * 3.14159 * (15 ft)^3

Simplify:
V = (4/3) * 3.14159 * 3375 ft^3

Multiply the constants:
V = 4.18879 * 3375 ft^3

Multiply the numbers:
V = 14137.166 ft^3

Therefore, the volume of the sphere, with a diameter of 30 feet, is approximately 14137.166 cubic feet.
