Question

Three cows are tied to the centre of a circular field of radius 14 m with a 7 m long rope. Each one is given equal sector by putting small height walls. Find how much area each cow is unable to graze from the field given to her. What values of farmer is seen from his act.

Answer 1

let the radius of larger circle be R and smaller cir. be r
pi R ^2 = 196pi-----(1)
pi r^2 = 49 pi---(2)
 (1) - (2) = 147 pi
now,tot. ungraced Ar =147pi
therefore147 pi/3 = area each cow is unable to graze = 49 pi

from this we can under stand that the farmer upholds the value of equality and conservation
