A spherical helium balloon has a diameter of 30 cm.

How much helium is needed to fill the balloon, in cubic centimeters?

Round your answer to the nearest centimeter

14130

pi/6 * 30^3

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

Given that the diameter of the balloon is 30 cm, we can find the radius by dividing the diameter by 2: r = d/2 = 30/2 = 15 cm.

Now, we can substitute this value into the formula and calculate the volume:
V = (4/3) * π * (15)^3 ≈ 14137.166941154067 cm^3.

Since we need to round our answer to the nearest centimeter, the final result is approximately 14137 cm^3.
