How do you calculate the circumference if you know the diameter?
Circumference is equal to 2 times pi (3.1416) times one half of the diameter (the radius). So, if the diameter is 2 cm, then the circumference would be the product of (2) times (3.1416) times (1), or 6.2832 cm. Circumference is equal to diameter times Pi. c = Pi * d diameter times pi
Does circumference times diameter equal pi?
No; circumference divided by diameter equals pi.
What is the purpose of pi?
Pi is basically the relationship between the circumference and diameter of a circle. (c/d). If you divide the circumference by the diameter you will always get pi, since C=Pi times d (or 2 times pi times radius), so circumference (C) divided by diameter (D) is Pi.
Why is the circumference of a circle diameter times pi or 2 radius times pi?
Because 2 times the radius is equal to the diameter of the circle
What is the circumference of a circle in terms of pi?
Pi times the diameter.
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
How do you find the circumference from the area?
Well, you find the area of a circle by multiplying (pi times radius2) or (pi times radius times radius). The radius is half of the diameter. The formula for the circumference is (pi times diameter). Multiply the radius times 2 to get the diameter. Multiply the diameter times pi.
How do you do circumference when you have a diameter?
Pi times the diameter.
What is the circumference of a circle whose diameter is 30 if pi is 3.14?
Circumference = pi times diameter, so 30 times pi
How do you calculate the circumference if you know the diameter?
Circumference is equal to 2 times pi (3.1416) times one half of the diameter (the radius). So, if the diameter is 2 cm, then the circumference would be the product of (2) times (3.1416) times (1), or 6.2832 cm. Circumference is equal to diameter times Pi. c = Pi * d diameter times pi
What is the circumference of a circle with a diameter of 6?
Since circumference equals pi times the diameter, if the diameter of a circle is 6, then its circumference is going to be pi times 6 or 6 pi.
What is the formula for finding the circumferance of a circle?
Either pi times the diameter or pi times twice the radius (which is the diameter)
What is the circile of 3.14 times its diameter?
The circumference of a circle is pi times its diameter, pi being approximately 3.14.
Does circumference times diameter equal pi?
No; circumference divided by diameter equals pi.
How do you find the circumference of a circle knowing only the diameter?
Circumference of a circle: pi times diameter
What is the equation to get the diameter from the circumference?
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
What is the purpose of pi?
Pi is basically the relationship between the circumference and diameter of a circle. (c/d). If you divide the circumference by the diameter you will always get pi, since C=Pi times d (or 2 times pi times radius), so circumference (C) divided by diameter (D) is Pi.
