The radius of a cylinder is increased by a factor of 3. the height of the cylinder is increased by a factor of 2. what is the effect of the increases on the volume of the cylinder? a) the volume of the cylinder increases by a factor of 6. b) the volume of the cylinder increases by a factor of 18. c) the volume of the cylinder increases by a factor of 12. d) the volume of the cylinder increases by a factor of 3 2 .

The answer is the option B

The volume of the cylinder increases by a factor of

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

------> original volume

In this problem

substitute in the formula

therefore

The volume of the cylinder increases by a factor of

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
