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.
Pi radius diameter?
Lets see: diameter is the longest line across a circle (goes through the center) radius is one half the diameter Pi is the ratio of the circumference to the diameter. (3.14159 .....)
What is circumference in terms of pi?
As pi is the ratio of the ratio of the circumference (C) of any circle to its diameter (d), the circumference of a circle in terms of pi is: C = pi x d The circumference of a circle is pi times its diameter or 2 pi times its radius (since a diameter is 2 times the radius).
How do you get the diameter from the radius?
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
What is radius if diameter is 8?
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
What is the ratio of the diameter of the length of its radius?
diameter to radius ratio (for same circle) is 2:1
Is the ratio of the radius to the diameter of all circles?
The ratio of radius to diameter for any circle is 1/2
Is radius and diameter ratio the same?
No because the radius of a circle is half of its diameter.
What is the ratio of the diameter of a circle to its radius?
0:5
What is the ratio of a circle with a radius of 8cm?
It depends on the ratio of what of the circle? Its circumference, diameter, area?
What is the ratio between a circles diameter and its radius?
It is: 2 to 1
What is the ratio of the length of the diameter of a circle to the length of its radius?
Length of diameter:length of radius = 2:1
Pi is the ratio of a circles circumfrance to its what?

Pi radius diameter?
Lets see: diameter is the longest line across a circle (goes through the center) radius is one half the diameter Pi is the ratio of the circumference to the diameter. (3.14159 .....)
The diameter of a big circle is 42 feet what is the ratio of the circle's radius to it's diameter?
Radius = 1/2 of diameter.The ratio is 1/2 = 0.5.That's true for all circles, from microscopic to humongous, doesn't matter.
If you want to find the ratio of a circle how do you do it?
I think you mean "radius". It's half of the diameter.
What is the ratio of a 24 inch diameter to a 12 inch radius?
The ratio is 1 : 1 since the two measures are equivalent.
