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 :-(

• precalc/trig help please -

Duh. you are correct. Thank you
