Cylinders A and B are right circular cylinders. The height hA of cylinder A is 3 m and its radius rA is 1.2 m. The height hB of cylinder B is 15 m and its radius rB is 1.2 m. How many times as great as VA, the volume of the smaller cylinder A, is VB, the volume of the larger cylinder B?

A. 3

B. 5

C.10

D. 25

it not 25 tho i got that when solving the equation but i cant seem to get it i need help pls.

5

Step-by-step explanation:

Volume of cylinder = Pi * radius^2 * height

A = Pi * 1.2^2 * 3 = 13.5

B = PI * 1.2^2 * 15 = 67.8

67.8 / 13.5 = 5

cant open file sorry!

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
