Question

A cow is tied with a rope of length 14m at the corner of rectangular field of dimesions 20m x 16m, find area of field in which cow can graze.

Answer 1

Area grazed by cow

$={\frac{1}{4}}^{th}$ area of circle

$=\frac{\pi r^2}{4}=\frac{3.14\times 14\times 14}{4}$

$=153.86m^2$

$\therefore$ Area grazed by cow

$=153.86m^2$
