Question

How do you find the volume of the sphere in terms of `pi` given `V=4/3pir^3` and r= 1.5m?

Answer 1

`V=4.5 pi " m"^3`

Explanation:

"in terms of `pi`" means that we leave `pi` in it's symbolic form.

So, to solve, plug the given value of `r` into the Volume equation:

`V=4/3 pi r^3`

`V=4/3 pi (1.5"m")^3`

`V=4/3 pi (3.375 "m"^3)`

`V=4.5 pi " m"^3`
