The content of several smaller cylinders ( 3 meter diameter and 6 meter height) were to be emptied into a larger cylinder(20 meter diameter and 10 meter height), how many smaller cylinders will fill up the larger cylinder?  Choose the correct choice from the following
A) 20  B) 10  C) 50  D) 74  E) 73

Rationale: calculate the volume of the larger cylinder and divide it by the volume of the smaller cylinder . volume of cylinder = π r 2 h larger cylinder volume = 3141.59 smaller cylinder volume = 42.41 therefore the number of cylinders b that can be filled to capacity = 3141.59 / 42.41 = 74.1 answer is d 74 smaller cylinders can be filled to capacity .
Answer: D
