Greatest RMS voltage generated in a circuluar loop antenna

[Winzer]

1. Homework Statement [/
What is the greatest RMS voltage generated in a circuluar loop antenna which is 30.0 cm in radius (also located 14.0 km away)

Homework Equations

$$V=wA$$

The Attempt at a Solution

So the frequency is 170MHz.
My question is how to deal with the root mean squared.
is it:
$$V=\frac{wA}{\sqrt 2}$$? A is area by the way

 

[Winzer]

do i perform $$V=\frac{wA}{\sqrt 2}$$
or do i need to intergrate since this is a continious distribution?
$$V_rms= \sqrt ( \frac{1}{r} \int_0^r (wA)^2 dr)$$

 

[Winzer]

anyone?
