The radius of a circular garden is 49 m. What would it cost to put a 4-round fence around this garden at a rate of 40 rupees per metre ?​

Answer 1

30.17 rupees

Step-by-step explanation:

pie x (49)^2 = 7543 cm2

cm2 to m = cm x cm

100 x 100 = 10000

7543/10000 = 0.7543m

Rs 40 per metre

40 x 0.7543 = 30.17 rupees
