Best ResponseYou've already chosen the best response.2" the area of one of the smaller circles is 48 pi in2" use this info to find the radius of the smaller circle

Best ResponseYou've already chosen the best response.0Would 48 be the diameter?

Best ResponseYou've already chosen the best response.2no, 48pi is the area

Best ResponseYou've already chosen the best response.0So would i do 48*pi? Im so confused on this :(

Best ResponseYou've already chosen the best response.2\[\Large A = \pi*r^2\] \[\Large 48\pi = \pi*r^2\] \[\Large 48 = r^2\] the pi's cancel. Solve for r

Best ResponseYou've already chosen the best response.0So this\[\sqrt{48}=r ^{2}\]

jim_thompson5910

Best ResponseYou've already chosen the best response.2more like \[\Large r = \sqrt{48}\]

Best ResponseYou've already chosen the best response.0Here's a quick answer: It appears that the smaller circle has a radius that is .5 the radius of the larger circle. When calculating area, when you double the size the area increases FOUR times. SO, area of larger circle = 4 * 48 = 192

Best ResponseYou've already chosen the best response.2Now use the circumference of a circle formula \[\Large C = 2*\pi*r\] You'll plug in r = 2*sqrt(48)

Best ResponseYou've already chosen the best response.2when you plug r = 2*sqrt(48) into that circumference formula, what do you get?
