Question

a horse is tied to a peg at one corner of a square shaped grass field of side 15m. by means of a 5m.long rope find 1. the area of that part of the field in which the horse can graze .2. the increase in the the grazing area if the rope were 10m. long instead of 5m. use π= 3.14​

Answer 1

Answer:

area that horse can graze=19.625

increase in area =58.785

Step-by-step explanation:

radius of smaller circle r₁= 5m

area that horse can graze= (π*r₁²)/4

                                               =(3.14*5*5)/4

                                              =19.625 m²

radius  after the extension of rope=r₂

area that horse graze after the extension of rope= (π*r₂²)/4

                                                                                 =(3.14*10*10)/4

                                                                                  =314/4

                                                                                   =78.5 m²

increase in area =area after- area before

                            =78.5-19.625

                             =58.785 m²
