Solar power incident on the earth is 1.3kWm^-2

Radius of the earth’s orbit = 1×10^11m

What is the solar power emitted in all directions?

What equation do I use to calculate this?

Answer by Jacy
Surface Area of the Earth: S = 4πr² = 4π(1×10^11)² = 12.566×10^22 m²

Q/S = 1.3 kW/m²

Hence, the solar power emitted in all directions is:

Q = 1.3 kW/m²(12.566×10^22) = 16.3×10^22 kW
