Question

A horse is tied to a pole with 14 m long string.Find the area where horse can graze.

Answer 1

Answer:

if a horse is tied to with 14 m string of radius of circle it can graze is 14 m

given=radius=14m

to find =area of grazing

solution= πr²

22× 14×14

7

22×2×14

44×14

616 m²

mark me as brainest

Answer 2

A horse is tied to a pole with 14m long string.

So, the horse can only move on a circle path or under that circle area.

The pole will be the centre of the circle made by the horse and the length of the string will be the radius of the circle.

Now, Area where the horse can graze is the circle whose radius,r = 14 m

So,

$\\ area \: of \: circle \: = \pi {r}^{2} \\ = \frac{22}{7} \times {14}^{2} \\ = \frac{22}{7} \times 14 \times 14 \\ = 22 \times 2 \times 14 \\ = 616 \: {m}^{2}$
