the area of a circular field is 3218 2/7.m2

find the cost of fencing the field at rate of rs.14/m.

Hi!

Area of the field is 3218 2/7 m2

= pi r2 = 22528/7 m2

r2 = (22528 x 7) / (22 x 7)

r2 = 1024

r =32 m

Circumference = 2 pi r

=2 x 22/7 x 32

= 64 x 22/7

Cost of fencing = 64 x 22/7 x 14

=64 x 44

=Rs. 2816

@Hey frnd here is your answer:

Area of Circular Field = 2 (3218 2/7 m2)

ATQ,

Area of Circle = r2(Pi)

= 22 / 7 * r2

3218*2 / 22 = r2

Then , Solve it u will get thee value of r . and then find the circumference . And then Multiply By thr Rate.

Hope it helped pls thumbs up

@ Cheers !
