Best ResponseYou've already chosen the best response.148 inches = diameter formula for circle: \(πr^2\) \(d/2 = r = radius\) \(48/2=24\) \( A = π*24^2\)<solve that for me

Best ResponseYou've already chosen the best response.1How did you get 1,799.22? \(24^2=24*24=576\\π*576=1808.64\)

Best ResponseYou've already chosen the best response.1dw:1435963854154:dw the side length = diameter of the circle

Best ResponseYou've already chosen the best response.1since you want to know how much cloth was cut from the square, you have to find the area of the circle

Best ResponseYou've already chosen the best response.1the formula for that is \(πr^2\)

Best ResponseYou've already chosen the best response.1you are given the diameter, not radius radius is half of the diameter and diameter = 48 so 48/2 = 24 radius = 24
