## Mackenzie2013 one year ago Find the volume of a sphere with a diameter of 17.2 cm, both in terms of π and as a number. Use 3.14 for π. Round your answers to the nearest tenth.

1. anonymous

v=4/3pi*r3

2. Mackenzie2013

17.2 times pi?

3. Zale101

How did you get that?

4. Zale101

Volume of a sphere is $$\Large \frac{4}{3}\pi r^3$$ r is the radius

5. Zale101

Your question has the diameter. Step 1: Change diameter to radius. Do you remember how to change diameter to radius? Step 2: Plug the radius into the volume formula 4/3 *pi* r^3
