Question

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 what time will be taken by the cow to grazes the whole field ?

Answer 1

since it is tied by a rope it will be able to eat the field in circular way
area of circle is πr^2
22/7×14×14
616sq..feet
days to eat
616sq..feet÷100sq..feet/day
6.16 dayss
6 complete day and half day

Answer 2

Answer:

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

Step-by-step explanation:

Length of the rope of cow = 14 feet

Area of the region grazed by the cow = π· Radius²

⇒ Area of the region grazed by the cow = 22/7 × 14 × 14

⇒ Area of the region grazed by the cow = 44 × 14

⇒ Area of the region grazed by the cow = 616 square feet

Now, given that cow grazes 100 square feet in one day

So, number of days required by cow to graze 616 square feet = 616/100 = 6.16 ≈ 7

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