FAQs:
Q1: Is this formula only for perfect spheres?
A1: Yes, this formula is specifically for perfect spheres. For shapes like ellipsoids, you’d need different formulas.
Q2: How should I measure the radius for accurate calculations?
A2: Ensure the radius ($r$) is measured from the center of the sphere to any point on its surface.
Q3: Can this formula be used for hollow spheres?
A3: No, this formula assumes a solid sphere. For hollow spheres, you’d need to subtract the surface area of the inner sphere from the outer sphere.
