The base radius of a cone is 6 inches, and the cone is 8 inches tall. To the nearest square inch, what is the area of the lateral surface of the cone?

  • math -

    Total surface area = πrs + πr^2

    Since πr^2 is the area of base, πrs = area of lateral surface.

    Use Pythagorean Theorem to find s, the distance along the side from tip to base.

    s^2 = h^2 + r^2

    I'll let you do the calculations.
