56 m. What would it cost to put a 3-
round fence around this garden at a
rate of 30 rupees per metre?

Answer 1

Answer:

circumference of circle- 2 x pie r

C= 2 x 22/7 x 56

C= 352

cost - 352x 30

10,560

for 3 rounds cost 10560 x 3

31,680 rs

Answer 2

Answer:

Step-by-step explanation:

c = 2 pi r

c = 2 *22/7* 56

c = 44*8

circumference = 352m

Cost = (352*3)/30

C = 1056/30

=Rs. 35.2 per metre
