Question

Fence is to be drawn around a ciruclar ground of radius 7 m what will be the total expenditure if cost of fencing it is rs 120/m

Answer 1

Answer:

Step-by-step explanation:

radius = 7 m

fencing of circular ground = perimeter of the ground

                                            = circumference of the circle ground

                                            =  2 x pi x r

                                           =   2 x (22/7) x 7

                                           =   44 m

cost of fencing for 1 m       =  rs. 120

cost of fencing for 44 m    =    120 x 44

                                           =    rs. 5280
