  1. Answer:

    Then cost of 2.0096 m2 polishing = 15 x 2.0096 = Rs 30.14 (approx.) Thus, the cost of polishing a circular table top is Rs 30.14 (approx.)

  2. Answer: Rs 30.144

    Step-by-step explanation:

    Area of circular table-top = πr²

    = 3.14 × (0.8)²

    = 2.0096 m²

    Cost of polishing @ Rs 15/m = 2.0096×15 Rs

    =30.144 Rs
