what is the largest circle which can be drawn from a square sheet with a side of 81cm? which area is greater, the circle or the square sheet?
the largest circle drawn in a square is by taking the diagonal as diameter of the circle .
now about circle, its dia = sq.root of(81^2 + 81^2) =114.5 cm
area = pi * r^2 = pi *(114.5/2)^2.-------- (1)
area of square = 81^2 -------- (2)
compare the answer of 1 & 2 you will get the answer.
