The total surface area in square meters is:

I have no idea how to figure this out, does anyone know? Please simplify your equation or whatever, as i do not know what to enter into my calculator if you say things like ^ 4/3 and etc thanks!

    Let:

    r be the radius,

    s be the slant height.

    The area of the base is:

    pi r^2.

    The area of the remaining part is:

    pi r sqrt(r^2 + h^2).

    Adding those together gives:

    pi r (r + sqrt(r^2 + h^2).

    pi * 6 * (6 + sqrt(6^2 + 8^2))

    = pi * 6 * (6 + sqrt(36 + 64))

    = pi * 6 * (6 + sqrt(100))

    = pi * 6 * (6 + 10)

    = pi * 6 * 16

    = pi * 96

    = 301.6.

    You evaluate expressions such as a^b using the [x^y] key:

    a [x^y] b.

    You will probably have keys labelled with the Greek letter [pi], [x^2] for doing the square, and with a square root sign for doing the square root.
