Academic Mathematics NCERT Class 10

Given: A cow is tied with a rope of length $14\ m$ at the corner of a rectangular field of dimensions $20\ m\times 16\ m$.

To do: To find the area of the field in which the cow can graze.

Solution:

Area grazed by cow $=\frac{1}{4}^{th}$ area of circle

$=\frac{1}{4}\times \pi r^2$

$=\frac{3.14\times14\times14}{4}$

$=153.86\ m^2$

$\therefore$ Area grazed by cow $=153.86\ m^2$
