Problem: Imagine there is a large star that produces 2.5 x 1030 Watts of power. If there is a planet orbiting this star from 500 million km away, how would you calculate the solar constant of this planet? Select all necessary steps. Assume you might need to convert units to complete the calculation.
Group of answer choices
- Find the surface area of a sphere with a radius of 500 million kilometers
- Find the surface area of a sphere with a diameter of 500 million kilometers
- Divide the solar output of the star (2.5 x 10^30 Watts) by the surface area of the sphere
- Multiply the solar output of the star (2.5 x 10^30 Watts) by the surface area of the sphere
