Question

Helpppp please
Find the volume of this object.
Use 3 for pi

Answer 1

The sphere

`v=(4)/(3) \pi r^(3)=(4)/(3)*3.14 *2^(3)=(4*3.14*8)/(3)=(100.48)/(3)=33.493`

The cylinder

`v=\pi r^(2) h=3.14*((4)/(2) )^(2)*3=3.14*2^(2)*3=9.42*4=37.68`

Add those two volumes together:

`33.493 + 37.68 = 71.173 in^(3)`
