Answer:
C is the answer
Step-by-step explanation:
First find the area of the circle -
Use pi times r^2
Since the answers are in pi form, we just need to do the "r^2" part. 3 is the radius, so 3 x 3 = 9. Now that we have found the area of the circle, we will need to multiply the area of the circle by the height of the cylinder. (9pi)(9) = 81pi cubic units. 81pi cubic units is the answer.
A and E, they are basically at the same point around
So n=8 and those are all the steps
12 x 12 = 144
20 x 12 = 240
=384
ANSWER: 384
