A circular field has an area 1256m2 .A horse is tied at the centre of the field with the help of a rope 15m long.how much area of the field will the horse be able to graze?Also find the area of the remaining field.
Answer :
We have our circular field , As :
Here length of rope = Radius of small circle that can be grazed by horse = 15 m
And we know
Area of circle =
So,
Area of field graze by horse =
Area of circular field = 1256 m2
So,
Area of remaining field = 1256 - 707.14 = 548.86 m2 ( Ans )
