Question

A goat is tied by a rope 2½m long to a peg in some grass. The goat eats 1m² of grass in 28minutes. How long does it take to eat all that can reach?

Answer 1

Answer:

549.5 minutes

Step-by-step explanation:

The goat can rototate in a circule the radius of the curcle is 2.5 m

So the area of circle is;

A=(pi) (r^2)

A=(3.14)(2.5)^2

A=19.625 m^2

As 28 minutes for 1 m^2 so;

Time taken to eat all = (28)(19.625)=549.5 minutes
