Question

a horse is tied to a pole in the park with a string 21m long find the area over which the horse can graze

Answer 1

The string will act as radius
The area in which horse graze will be a circle
Required area =
$\pi \: r {}^{2} \\ 22 \div 7 \times 21 \times 21 \\ 22 \times 3 \times 21 \\ 66 \times 21 = 1386$
It is the answer

Answer 2

horse can graze in a circular of radius 21m So, area over which the horse can graze = πr^2 = 22/7*21*21 = 22*21*3 = 462*3 = 1386 sq. metre. please please mark me as brainliest
