Answer:

$-i$

Step-by-step explanation:

We use the fact that $i^{2} =-1$ to rewrite the expression and simplify :

$i^{43} =i-^{42} * i\\=(i^{2} )^{21} *i\\=(-1)^{21} *i\\\\=-i$

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 $32 \pi$
