A circular field has an area 1256 m² A horse is tied at the centre of the field with the help of a rope
15 m long. How much area of the field will the horse be able to graze! Also find the area of the
remaining field.​

Answer 1

Answer:

548.86 m2

and pls mark me as brainliest

Step-by-step explanation:

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  = π r2π r2

So,

Area of field graze by horse  = 227× 15 × 15 = 49507 = 707.14 m2                                   ( Ans )227× 15 × 15 = 49507 = 707.14 m2                                   ( Ans )

Area of circular field  =  1256 m2

So,

Area of remaining field  =  1256  - 707.14  = ​548.86 m2                                  ( Ans )
