Question

A spherical balloon has a diameter of 4 feet. Approximate how many cubic feet of air this balloon holds. Use 3.14 as an approximation for , and give a numerical answer.

Answer 1

Answer: 4.05

Step-by-step explanation: The equation 4/3(pi)r^3 can be used to find the volume of a sphere. Since radius is just the diameter divided by two, the radius in this case is 2. If we plug the values into the equation, you will get 4/3(3.14)2^3, which, if you work it out, is 4.03 feet cubed.
