Question

Find the cost of polishing a circular table-top of diameter 1.6 m, if
the rate of polishing is 15/m. (Take it=3.14)​

Answer 1

Answer:

area of a circle= pi*r*r

radius of table=1.6/2

                        =160(converted to cm)/2

                        =80

area of the table top=

                                   =3.14*80*80

                                   =20,096/100 (converting back to m)

                                   = 200.96

cost of polishing =200.96*15

                            =3,014.4
