Question

a cow is tied to one corner of a square plot of side 10 metre with a rope 6 metre long.find the area that cow can't graze​

Answer 1

Answer:

R=6m

Step-by-step explanation:

Area covered by cow =1/4*22/7*6*6

28. 27m2

Answer 2

Answer:

The cow cannot graze 71.74m² of the plot.

Step-by-step explanation:

Given that:

The cow is tied to one corner of a square plot of 10m with a rope 6m

As the cow is tied at the corner of the plot, it will be able to graze the plot lying in the quarter of radius 6m

We know that area of a quarter = $\frac{1}{4}$ * πr²

Therefore, the area the cow can graze =  $\frac{1}{4}$ * π * 6²

                                                                 = 9π

                                                                 = 9 * 3.14

                                                                 = 28.26m²

We need to find the area that cow can't graze

= Area of the plot - The area that the cow can graze

= 10² - 28.26

= 100 - 28.26

= 71.74m²

Therefore, the cow cannot graze 71.74m² of the plot.
