rounds-​

Answer 1

Answer:

28×5=140

Step-by-step explanation:

140m the distance covered in 5 round.

Answer 2

Answer:

Answer

As the garden is in the shape of circle.

Therefore,

Diameter of garden =28m(Given)

⇒ Radius of garden (r)=

2

28

=14m

As we know that circumference of the circle is given by-

Circumference =2πr

where as, r is the radius of circle.

Therefore,

Circumference of garden =2×

7

22

×14=88m

For 3 rounf of fence,

Length of wire required =3×88=264m

Given that the cost of wire is Rs.30 per m

Therefore,

Cost of wire =30×264=Rs.792.

Hence the length of wire required is 264m and the cost of required wire will be Rs.792.
