Question

7. A Cow is tied with a rope of length 14m at the corner of a rectangular field of dimensions 20m X
16m then the area of the field in which the cow can graze is​

Answer 1

Answer:

area of field =20×16

= 320 m²

area of one-fourth circle =1/4 pai r²

= 1/4 × 14 × 22/7 × 14

= 154 m²

Step-by-step explanation:

dear , solution is find from only the formula of one-fourth circle no need to find area of field ; but i find because i think there finding thing is area which cow can't graze .

Answer 2

Area grazed by cow

= ¼th area of circle

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

=153.86m²

∴ Area grazed by cow

=153.86m²
