Multiply the radius by (2 x pi) to get the circumference.
-5(7m + 9) -7m
The goat can graze a quarter circle of radius 7m (since the rope length is 7m) within the square plot of 12m. Hence the area it can graze can be given by /4. Therefore (3.14*7*7)/4=38.5sq.m
7m-5 = 9 7m = 9+5 7m = 14 m = 2
7m = 700cm, so 732cm is longer than 7m.
