I need help with this

756pi  unit^3.

Step-by-step explanation:

This is the sum of the volume of 3 spheres

V of a sphere = 4/3 pi r^3, so we have:

4/3 pi 2^3 + 4/3 pi 6^3 + 4/3 pi 7^3

= 4/3pi (2^3 + 6^3 + 7^3)

= 756pi.

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !

is it like a multiple choice? if so then i need the multiple choice so i can get and understanding on what the answers is so that i can explain it to you
