Question 1141634
 A goat is tied to a rope which can slide along a straight line wire 10 m. 
Find the area in which that goat can graze if the rope is 3.5 m long. 
:
Assuming the rope can extend outward from the two ends of the 10m wire,
to form a semi-circle of a radius of 3.5m on each end
A = (2(3.5) * 10) + {{{pi*3.5^2}}}
A = 70 + 38.48
A = 108.48 sq/m
