Question

Find the distance covered by a cow tied with a rope 3.5 m long to a pole if it completes 1 round makin the rope stretched.......I will mark u as brainiest only if you answer in detail

Answer 1

Answer: 22m

According to the question--- Radius=3.5m

1 round=1 circumference

Circumference = 2πr

2*22/7*3.5=2*22*0.5=44*0.5=22

Hope it helps you

Answer 2

Step-by-step explanation:

The cow is tied to a pole with a rope. The rope is fully stretched while the cow is making the round. around the pole, the cow is moving in a circle. So, the length of the rope will be the radius of the circle.

Distance covered by the cow in on round= Circumference of circle

Radius of circle= 3.5m

Circumference of circle= 2πr

Circumference of circle= 2 x 22/7 x 3.5

Circumference of circle=2 x 22 x 0.5  (Cancelling 7 and 3.5= 0.5)

Circumference of circle= 44 x 0.5

Circumference of circle= 22m

Hence, distance covered by cow in 1 round= 22m

Hope its clear!!
