Question

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? (5 points)
Select one:
a. Cylinder B is 50% smaller than cylinder A.
b. Cylinder B is 75% smaller than cylinder A.
c. Cylinder B is 150% bigger than cylinder A.
d. Cylinder B is 200% bigger than cylinder A.

Answer 1

Answer 2

start by finding the Volume of cylinder A

Answer 3

do u have the formula handy ?

Answer 4

Volume of cylinder = \(\large \pi *r^2*h\)

Answer 5

i forgot the formula all geometry is is formualas

Answer 6

what is the radius and the height

Answer 7

@ganeshie8

Answer 8

ok i got it
pi* 10^2*5

Answer 9

yes, so that equals 500pi

Answer 10

so what am i supposed to do now

Answer 11

percent change =
\(\large \frac{750\pi - 500\pi }{500 \pi} = \frac{250}{500} = \frac{1}{2}\)

Answer 12

multiply it wid 100

u wud get % change = 50

Answer 13

so the answer is A

Answer 14

nope, A is not the answer

Answer 15

c. Cylinder B is 150% bigger than cylinder A.

Answer 16

100+50 = 150

Answer 17

so C i totally get this:) thanks

Answer 18

good to hear :)
