Question

Find the length of the rope by which a bull must be tethered in order that it may be able to graze an area of 2464m.

Answer 1

Answer:

28 m

Step-by-step explanation:

area grazed by the bull must be circle of radius equal to the length of yhe of the rope  and let this length be r

therefore

πr^2 = 2464

r^2= 2464/π= 112×7 = 784

$r= \sqrt{784}$

r= 28 m

therefore the length of the rope = 28 m

Answer 2

The length of the rope is 28.012 meter.

Step-by-step explanation:

Given :  Rope by which a bull must be tethered in order that it may be able to graze an area of 2464 m².

To find : The length of the rope ?

Solution :

The bull will graze a circular field of area 2464 m² and radius equal to the length of the rope.

Let the length of the rope be r meter.

So, Area of field is $A=\pi r^2$

$2464=3.14\times r^2$

$r^2=\frac{2464}{3.14}$

$r^2=784.7133$

$r=\sqrt{784.7133}$

$r=28.012$

Therefore, the length of the rope is 28.012 meter.
