What is the difference between the formulas for these circular solids?
The formulas for different circular solids are:
1. Formula for the area of a circle: A = πr^2
2. Formula for the circumference of a circle: C = 2πr
3. Formula for the surface area of a sphere: A = 4πr^2
4. Formula for the volume of a sphere: V = (4/3)πr^3
The main difference between these formulas is the dimension they represent. The area and circumference formulas are for two-dimensional shapes (circle), whereas the surface area and volume formulas are for three-dimensional shapes (sphere). Additionally, the formulas for area and circumference involve only the radius (r) of the circle, while the formulas for surface area and volume of a sphere also include the radius (r) but raised to a different power.
