Question

a radius of a circular Garden is 28 meter what would it cost to put a 4 round fence around his Garden and a rate of 30 rupees per metre

right ans will be the brainliest​

Answer 1

Answer:As the garden is in the shape of a 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 round 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.7920.

Hence the length of wire required is 264m and the cost of required wire will be Rs.7920.

Answer 2

Answer:

5280M

Step-by-step explanation:

CIRCUMFERENCE IS 176m

176m MULTIPLIED BY 30=5280

hence the answer is 5280m
