Help show work and explain thanks

Answer 1

First of all, there are a few things you should know:

1) Area of a cylinder: $\pi r^{2} h$
2) Area of a cone: $\frac{1}{3} \pi r^{2} h$

To solve this, just plug it in:

Cylinder: $\pi * 2^{2} * 7 = 28 \pi$
Cone: $\frac{1}{3} * \pi * 2^{2} * 3 = 4 \pi$

The total is $32 \pi$
