Question

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.

Answer 1

v=4/3pi*r3

Answer 2

17.2 times pi?

Answer 3

How did you get that?

Answer 4

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

Answer 5

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
