Answer:
The circumference of a circle can be calculated using two formulas: C = 2πr or C = πd, where π is a mathematical constant roughly equal to 3.14, r is equal to the radius, and d is equal to the diameter.
The area of a circle can be determined using either the diameter or the radius using two alternative formulas: A = πr^2 or A = π(d/2)^2, where π is a mathematical constant roughly equal to 3.14, r is the radius, and d is the diameter.
