Why are there two formulas to calculate the circumference of a circle?
They are: 2*pi*radius or as diameter*pi
Explain how the two circumference formulas are related to each other?
The two common circumference formulas are (C = 2\pi r) and (C = \pi d), where (C) represents the circumference, (r) is the radius, and (d) is the diameter. These formulas are related through the relationship (d = 2r), meaning the diameter is twice the radius. Thus, substituting (d) in the second formula gives (C = \pi (2r) = 2\pi r), showing that both formulas describe the same concept of circumference in terms of different circle dimensions.
