Best ResponseYou've already chosen the best response.1I double checked it and I am always getting (128pi)/9 or 44.68

Best ResponseYou've already chosen the best response.1Sub in values: pi*8^2 * 80/360 = 128pi/9

Best ResponseYou've already chosen the best response.1maybe the book has a typo Isn't it that Area of sector = (1/2) (r^2) (theta) theta is in radians

Best ResponseYou've already chosen the best response.1\[Area = \frac{1}{2} \times 64 \times 80 \times \frac{\pi}{180} \implies 44.65\]

Best ResponseYou've already chosen the best response.1@waterineyes I think it should be 44.68 ? :)

Best ResponseYou've already chosen the best response.1Actually it can be: \[Area = 44.698\]

Best ResponseYou've already chosen the best response.1As value of \(\pi\) is not exact so you cannot say about the exact value..

Best ResponseYou've already chosen the best response.1Here we all are approximating this value..
