Question

the path of uniform widh 5 m runs around a circular field of radius 86 m . find the area of path​

Answer 1

Answer:

Area of path would be 2780 m^2

Step-by-step explanation:

π(91^2-86^2) =2780

Answer 2

Answer:

THE ANSWER IS 2778.9m²

Hope you can understand and find it helpful!

Step-by-step explanation:

GIVEN,

    Width of path=5m

    Radius of the circle = 86m(without the width of the road)

   ∴Radius of the circle = 91m(with the width of the road)

Now,

    Area of the circle without the width of road = πr²

                                                                              =3.14×(86)²

                                                                              =23223.44m²

Now,

     Area of the circle with the width of road = πr²

                                                                              =3.14×(91)²

                                                                               =26002.34m²

Now,

Area of the road = (Area of the circle with the width of road - Area of the   circle without the width of road)

                           = (26002.34-23223.44)m²

                           =2778.9m²

∴Area of the road/path = 2778.9m²
