Question

In a grassland, a sheep is tethered by a rope of length 4.9 m. Find the maximum area that the sheep can graze

Sum

Solution

Length of the rope = 4.9 m

Area that the sheep can graze = Area of circle with radius 4.9 m

Area of the circle = πr2 sq.units

= `22/7 xx 4.9 xx 4.9`

= 22 × 0.7 × 4.9

= 75.46

∴ Area that the sheep can graze = 75.46 m2
