Best ResponseYou've already chosen the best response.1I used the formula of 1/4 of a circle :)

Best ResponseYou've already chosen the best response.1Actually you should use area of a sector, where angle is Pi/4.

Best ResponseYou've already chosen the best response.1ohhh, so it is better to use the area of sector formula?

Best ResponseYou've already chosen the best response.1Area of sector is ( Theta/2) x r^2. WHere theta is in radians.

Best ResponseYou've already chosen the best response.1@ganeshie8 Thanks, I made an arithmetic error with the area with radius 40 :)

Best ResponseYou've already chosen the best response.1@Champs Which do you think is the better thing to use (although the result will be the same) ? area of sector formula or area of 1/4 of a circle? please explain :)

Best ResponseYou've already chosen the best response.1hmm i have used 1/4 of circle area as it looked obvious at first glance. but as you said it is same thing as sector formula eh ? in sector formula we multiply the area by a factor of : \(\frac{\pi/2}{2\pi} \) = 1/4 both sector formula and area of 1/4 of a circle give the same factor :P

Best ResponseYou've already chosen the best response.1It is better to use area of sector otherwise you'd face problem when the angle is not =90 deg.

Best ResponseYou've already chosen the best response.1@Champs oh. That makes sense. Thanks for the reminder I will remember that. :) I'll also try to solve this with area of sector. :)
