Question

A horse is tied to a pole with 28 m long string. Find the area where the horse can graze. (Take π = 22/7).

Answer 1

We have :
Length of the string = ​28 m
The area over which the horse can graze is the same as the area of a circle of radius 28 m.
Hence, required area = π​r² = $\left(\frac{22}{7}\times 28\times 28\right){\mathrm{m}}^2=\left(22\times 4\times 28\times \right){\mathrm{m}}^2=2464{\mathrm{m}}^2$.
