Help plz show work please

Answer 1

471.24

Explanation:

Alright, so we have 2 cones. One cone, let's call this cone a, has a height of 7, and cone b has a height of 11. Both cones have a base radius of 5. This is all given info.

Fair enough. We can go from here. Let's plug the values into the equations for the cone and then add cones A and B together.

The equation/formula for volume of a cone is:

`V_(cone) =(1)/(3) \pi r^(2) h`

Cone A:

`=(1)/(3) \pi r^(2) h\\\\=(1)/(3) \pi (5)^(2) (7)\\\\=(175\pi )/(3) \\=183.26`

Cone B:

`=(1)/(3) \pi r^(2) h\\\\=(1)/(3) \pi (5)^(2) (11)\\\\=(275\pi )/(3) \\=287.98`

Now we add:

287.98 + 183.26 = 471.24

Hope this helps, let me know if I missed anything!
