Answer:
the answer is c) 182.25
Step-by-step explanation:
The information provided gives you a scale that will ultimately allow you to determine the height of the larger cylinder.
Since it tells us the two are similar, we can use the scale to solve for the second height.
Set up your math like this:

h represents the height you are trying to find.
using a common multiple, you can solve for h.
16 times 4 is 64. so 729 divided by 4 is 182.25
They forget to say "not to scale". I'm guessing this is trig because I don't see another way to do it.
Let's consider x=chord PQ first. By the Law of Cosines

We have an isosceles triangle formed by two radii of 9 cm and x=PQ. By the Law of Cosines again,





The area of the circle is the fraction given by the angle,
