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
Are there many formulas to calculate pi?
Pi = circumference/diameter
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
