Best ResponseYou've already chosen the best response.0Part B the radius increases by 2 so area = pi * 6^2

Best ResponseYou've already chosen the best response.0@Chumpian How did you get that?

Best ResponseYou've already chosen the best response.0\[A = \pi r^2\] so 4 is the radius (r) and what's 4 squared?

Best ResponseYou've already chosen the best response.0yep and they want the answer in terms of pi so 16pi is your answer

Best ResponseYou've already chosen the best response.0So again you use the equation \[A = \pi r^2\]

Best ResponseYou've already chosen the best response.0area = pi r^2 where r = radius r is now 6 so its pi * 6^2 = 36 pi

Best ResponseYou've already chosen the best response.0We are doing the same thing as we did in part A

Best ResponseYou've already chosen the best response.0so what do we do with the radius that equals 6

anonymous

Best ResponseYou've already chosen the best response.0but we are doing the same thing as Part A but just with a larger radius

Best ResponseYou've already chosen the best response.0So when we plug in the 6 \[A = \pi 6^2\]

Best ResponseYou've already chosen the best response.0What do you do with the 6?

Best ResponseYou've already chosen the best response.0multiply is by itself so 12

Best ResponseYou've already chosen the best response.0that would be 6 x 2 = 12 but squaring a number would be 6 x 6 = 36

Best ResponseYou've already chosen the best response.0yep and they want it in terms of pi So your answer is?
