To solve this problem you must apply the proccedure shown below:
You have that the radius of the cylinder is 2.75 inches and the height is 5.21 inches. Therefore, you only need to substitute these values into the formula for calculate the volume of a cylinder:

Therefore, as you can see, the answer is: The volume of the cylinder is 124 in³.
Step-by-step explanation:
a. that's the best answer that suits the question per day you multiply by 22
Supplementary angles add up to 180 degrees
ratio of 1:4.....added = 5
1/5(180) = 180/5 = 36 <=== smaller angle
4/5(180) = 720/5 = 144 .... larger angle
Answer:
the answer for that question is sqrt(49)
