Why are there two formulas to calculate the circumference of a circle?
They are: 2*pi*radius or as diameter*pi
What are 2 math formulas which include pi?
Two common math formulas that include pi are the area of a circle, given by ( A = \pi r^2 ), where ( r ) is the radius, and the circumference of a circle, which is ( C = 2\pi r ). Both formulas highlight the relationship between a circle's dimensions and the constant pi, approximately equal to 3.14159.
What are the two formulas for circumference?
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
What are the two formulas pertaining to circles that pi is used in?
Angular measure of a circle: 2*pi radians. Circumference of a circle with diameter d units: d*pi units
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.

Are there many formulas to calculate pi?
Pi = circumference/diameter
Is pi in formulas?
Yes. Some examples of formulas that contain pi (∏) are: (area of a circle) = ∏r2 (Circumfrance of a circle) = ∏d
What are two possible formulas for finding the circumference of a circle?
Circumference = pi x the diameter / pi x twice the radius / pi x square root of "area divided by pi". C = (pi) D C = 2 (pi) r C = 2 (pi) * [sq rt (A/pi)] r = radius D = diameter pi = 22/7 or 3.14
