Answer:


Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of sphere.
Volume =

Notice that our sphere has a radius of 18 units, so we can plug 18 into the formula.
Volume =

Now, let's start by simplifying the exponent.
is equal to 18 units x 18 units x 18 units or 5,832 units³.
Volume =

Notice that we can cross cancel 3 in
and 5,832 to 1 and 1,944.
Volume =

Volume =
