Answer:
25:36
Step-by-step explanation:
The area grazed by both the goats will be circular in shape as they are moving at a constant distance from a fixed point.
Hence, the area grazed when a goat is tied at a point with a rope would be a circle with radius equal to the length of the rope.
Area of a circle =
π
r

.
Hence, the required ratio =
