Question

Could someone help me understand this question? I got 150% bigger and that isn't a choice option

Cylinder A has a radius of 10 inches and a height of 5 inches. Cylinder B has a volume of 750π. What is the percent change in volume between cylinders A and B?

Cylinder B is 50% smaller than cylinder A.

Cylinder B is 75% smaller than cylinder A.

Cylinder B is 50% bigger than cylinder A.

Cylinder B is 200% bigger than cylinder A.

Answer 1

What are the volumes of A and B? Did you find that already?

Answer 2

The volume of A is 1570 and the volume of B is 2355

Answer 3

1570/2355= .66666666

Answer 4

oh hold on,
scratch that
the first step you must do is find the difference between the two cylinders

Answer 5

what's 750 pi - 500 pi?

Answer 6

ok :) the difference is 785

Answer 7

or 250 pi

Answer 8

Now that set 250pi/500 pi, the difference of volume is 1/2 or 50 percent of volume A

Answer 9

so cylinder B is 50% larger than cylinder A...right?

Answer 10

Jane jane jane, you have the right idea with 150%.
Cylinder B's volume is 150% the size of Cylinder A's.
Or in other words, 50% larger. 100% the same, and 50% MORE.

Answer 11

and it's not on there, so let's look at another way
The raio of the two volumes is
750pi/500 pi = 1.5

Answer 12

so cylinder B is 150% more than cylinder A

Answer 13

but thats not an answer choice :(

Answer 14

Cylinder B is 150% of cylinder A,
or
Cylinder B is Cylinder A + 50% MORE.
yes?

Doesn't that sound like option C maybe? c:

Answer 15

Yep option C :)

Answer 16
