The area of a circle is 18pi square meters. What is the radius (leaving answer in simplest radical form)

  • precalc/trig help please -

    pi*R^2 = 18*pi
    R^2 = 18
    R = 3*sqrt2 m^2 = = 4.24 m^2

  • precalc/trig - PS -

    That would be in m, not m^2 :-(

    Duh. you are correct. Thank you
