The average intensity of sunlight at earth's surface is approximately 1400 W/m^2 , if the Sun is directly overhead. The average distance between the earth and the sun is 1.50E11 m. What is the average power emitted by the Sun?
Ok so intensity is power over area.
so power is intensity area, how do I get the area?
Am I approaching this problem correctly?

Physics 
Raquel,
I used 4*pi*r^2 for the Area and got 3.96E26 W for the Power is that right?
