Question:
Horse tied with rope in the center of square lawn length of the rope is 7cm find the area of the lawn which the horse can graze
Answer:
Length of rope is the radius of the circle r = 7 cm
Since the horse is tied at one end of the square field, it will graze only quarter of the field with radius 7 cm.
Now, Area of circle = πr2 = 3.14 × 72 = 3.14*7*7 = 153.86 cm2
Area of that part of the field in which the horse can graze = 1/4 of area of the circle = 153.86/4 = 38.465 cm2
