Question

A horse is tied to a pole in a park with a string twenty one meter long find the area over which the horse can graze

Answer 1

area the horse will be able to graze= area of circle

therefore, area of circle =

$\pi {r}^{2}$

thus,

$\frac{22}{7} \times 21 \times 21 \\ 22 \times 3 \times 21 \\ = 1386 {m}^{2}$

therefore the horse will be able to graze 1386
