You are to paint the globe held aloft by a statue of Atlas. Its diameter is 10.5 in. How much surface area must you cover with paint if 27 square inches does not need to be painted (to the nearest hundredth)?

  • Math -

    Surface area = 4 pi r 2

    A = 4 * 3.14 * 5.25^2

    A = 4 * 3.14 * 27.5625

    A = 346.105 square inches

    Subtract 27 from the total.
