Question

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

Answer 1

Answer:

⇒ r=28m [ Given ]

⇒ Area which horse can graze =πr²

⇒ Area which horse can graze = 7/22x(28)²

⇒ Area which horse can graze =22×28×4=2464m²

Answer 2

Answer:

A horse is tied to a pole with 14 m 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 .

Where, r = 14m

So,

$Area \: of \: circle = πr²\: \\ = \frac{22}{7} \times( {14})^{2} \\ = \frac{22}{7} \times 14 \times 14 \\ = 22 \times 2 \times 14 \\ = 616 {m}^{2}$
