Question

Give the equations for finding:    
*   the *circumference* and *area* of a circle    
*   the *surface area* and *volume* of a sphere

Accepted Answer

*circumference* of a circle: $$C = 2\pi r$$    
*area* of a circle: $$A = \pi r^2$$    

*surface area* of a sphere: $$SA = 4\pi r^2$$    
*volume* of a sphere: $$V = \frac{4}{3}\pi r^3$$, where *r* is the radius
