Answer 2

Volume of a cylinder is?

Answer 3

pir^2h

Answer 4

When I plug in the formula,
I get: 502.65

Answer 5

502.65=(pi)*(4^2)*(10), right?
What's 20% converted to a decimal? 0.2 and thus, a 20% increase to x would be x*1.2
So it's 502.65*1.2=603.18
So now the volume is 603.18
What part of the previous equation (pi)*(4^2)*(10) is constant, and what part of it is being changed?

Answer 6

10

Answer 7

@ijakez

Answer 8

Yep! so 603.18=16*pi*(the new height)
So simply divide both sides by 16pi to find the new height.
603.18/16pi=12 yay!

Answer 9

Wait... I got something different.

Answer 10

is your calculator in degrees?
should be radians

Answer 11

118.434

Answer 12

PEMDAS! 603.18/16pi=12

Parenthesis? None
Exponents? None
Multiplication? 16*pi BEFORE you divide.
You're dividing 603.18/16 and then multiplying the answer by pi.
Instead, you divide 603.18/(16*pi), if the parenthesis help.
