This is a right triangle, the measure of angle A is 90 degrees.
First thing to do I guess is finding B and C.
tan^-1 (7/12) = 30 degrees
tan^-1 (12/7) = 60 degrees
60 + 30 = 90
180 - 90 = 90. Therefore angle A = 90 degrees
Answer:
288π
Step-by-step explanation:
The equation for the volume of a cylinder is V=πr²h
So, To do this you would plug in the values that are given.
The radius would be 4 because it is half the diameter.
And the height is 18
So V=π(4)²(18)
So you just multiply the numbers and not the pi to get 288π
