Answer:

Step-by-step explanation:

Radius of the table top = 7/2

Area of the table top = area of the circle = π r^{2}

                                   = (22/ 7)  * 7/2 * 7/2

                                   = 22 * 1/2 *7/2

                                   = 11 * 7/2

                                   = 77/2 = 38.5m^2

Cost of polishing table top per m^2 = Rs. 60

Total cost of polishing 38.5 m^2 of area = 38.5 * 60

                                                                   = 385 * 6

                                                                   = Rs. 2310
