## Answer :

[tex] \pi r^{2} /4[/tex]

so

find The Area of A circle With of Radius 15m and divide it with 4

that"s it The answer given

horse can graze part of 39.25 if the rope is increased to 10 then it will be 628

FIND;

1. The area of that part of the field in which the horse can graze.

2. The the increase in area if the rope was 10 m long instead of 5. [use pie as 3.14]
