Answer 2

Answer:

The cow grazes the whole field in 7 days.

Step-by-step explanation:

Given : A cow is tethered in the middle of a field with a 14 feet long rope . If the cow grazes 100 sq. ft. per day then approximately.

To find : What time will be taken by the cow to grazes the whole field ?

Solution :

Length of the rope of cow = 14 feet

Area of the region grazed by the cow $A=\pi r^2$

$A=\frac{22}{7}\times 14^2$

$A=\frac{22}{7}\times 196$

$A=616\ ft^2$

Cow grazes 100 square feet in one day.

So, number of days required by cow to graze 616 square feet is

$n=\frac{616}{100}$

$n=6.16$

$n\approx 7$

Therefore, The cow grazes the whole field in 7 days.
