How do you find the circumfrance of a cirlce if you know the diameter?
You multiply the diameter by Pi, that is 3.14159 (to the nearest 5th decimal). circumf. = dia. x Pi.
What do diameter and circumfrance have to do with pi?
In any circle, the ratio of circumference to diameter is (pi).
How do you figure out the circumfrance?
Circumference = 2*pi*radius or diameter*pi
If a circle is 3.9 meters in diameter what is its circumfrance?
3.9 x 3.14 m
What is diameter if circumfrance is 10 feet?
10/pi = 3.1831 feet (rounded)
How do you find circumfrance using diameter?
circumference of a circle = pi*diameter or 2*pi*radius
What is the diameter of a circle that has a circumfrance of 21.98m?
The diameter should be 7m.
What is the diameter of a circle times pie?
Here are the three circle equations, in words and equations. Circumfwerence - pi X diameter C = pi d Circumference = two X pi X radius C = 2pi r Area = pi X radius squared A = pi r^(2) NB It is only the radial value that is squared ; NOT 'pi'. NB pi is a constant at 3.141592..., usually approximated to 3.14 or 3.1416.

How do you findthe diameter if i have the circumfrance?
Divide the circumference by pi.
Is the ratio of a circumfrance to its diameter called pi?
yes
Pi is the ratio of a circles circumfrance to its what?
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
How do you figure out the circumfrance?
Circumference = 2*pi*radius or diameter*pi
Circumfrance of a 1.25 diameter?
To find the circumference of a circle, you have to multiply Pi and the Diameter. This means that to work out the answer you multiply Pi by 1.25. This equals 3.92699081, which rounded equals 3.93 (2dp) - the circumference of a circle with a 1.25 diameter.
If a circle is 3.9 meters in diameter what is its circumfrance?
3.9 x 3.14 m
What is diameter if circumfrance is 10 feet?
10/pi = 3.1831 feet (rounded)
