Question

To fence a circular plot of land,at 75p per m,costsRs33.find the radius of the plot?

Answer 1

Answer:

Step-by-step explanation:

The circumference of the circular plot = 2πr

                                                                = 2 × 22/7  × r

Since, cost of fencing per metre is 75 paise,

total cost of fencing =  Total circumference  × 0.75

33 = 2 × 22/7 × r × 0.75

     = 33/7 × r

→ r =   33 × 7    =   1 m                                

              33

Therefore, radius of the plot = 1 m
