Answer:
The formula for the volume of a cylinder is r^2piH.
Step-by-step explanation:
The process is to find the radius and square it, the radius is half of the top or bottom circle. And then you can get a calculator and multiply it by pi, or 3.14, or 3.141592653... Then you multiply it by the height. So the answer for this cylinder 200pi, or 628.3185307, you can round however you need to

So firstly you are given the external angles, to find the internal angles, you do 180-133=47
180-142=38
the internal angles in a triangle add up to 180, therefore it is
47+38=85
180-85=95
because you have to find the external angle=n you then need to take 95 away from 180
180-95=85
so the answer is A
