Answer 1

Answer:

cost=14067.2

Step-by-step explanation:

circumference= 2$\pi$r

circumference=2 x 3.14 x 56

circumference = 351.68

fence=351.68 x 40

cost=14067.2

Answer 2

Step-by-step explanation:

Radius = 56m

Circumference = 2πr

4 ROUND fence = 4(2πr)

C = 2x22/7x56

= 2x22x8

=44x8

=4(352)

=1408 m

₹40 per metre

= 1408 x 40

= 56,320

TOTAL COST = ₹56, 320
