First off, this question seems very strange becausea) the circumfrence of the Sun is more like 4,4 billion meters, andb) "area" is a general term that I have to assume means the surface area. I am going to take this question as: The circumfrence of a sphere is 528,3 m. What is its surface area? What we would do here is use what formulas we know about circles and spheres to find the radius from the circumfrence, and then find the surface area. C=2πr where C=circumfrence and r=radius. π ≈ 3,141592… 528,3=2πr 264,15=πr 84,0815564 ≈ rSA (sphere)=4πr² where SA=surface area and r=radius. SA ≈ 4π (84,0815564) ²SA ≈ 4π (7069,70813) SA ≈ 28278,8325πSA ≈ 88840,5724 m²
