Question

find the volume of a balloon with a diameter of 15 centimeters. use ( pi = 3.14 ). round your answer to the nearest whole number. use the keypad to type your answer in the box.

Explanation:

Step1: Find the radius

The radius \(r\) is half of the diameter. Given diameter \(d = 15\) cm, so \(r=\frac{d}{2}=\frac{15}{2}=7.5\) cm.

Step2: Use the volume formula for a sphere

The volume formula for a sphere is \(V=\frac{4}{3}\pi r^{3}\). Substitute \(r = 7.5\) cm and \(\pi=3.14\) into the formula.
