diameter to radius ratio (for same circle) is 2:1

The ratio of radius to diameter for any circle is 1/2

No because the radius of a circle is half of its diameter.

0:5

This is very, very basic math. The radius is half of the diameter. My 9 year old daughter knows this.

It depends on the ratio of what of the circle? Its circumference, diameter, area?

It is: 2 to 1

Length of diameter:length of radius = 2:1

pi

diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.

The ratio is 1 : 1 since the two measures are equivalent.

I think you mean "radius". It's half of the 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 .....)

Pi represents the ratio of the circumference of a circle to its diameter. If you know the diameter (D), then the circumference (c) is (D) *pi. If you know the circumference (C), then the diameter (D) is (C)/pi. circumference is 2PiRR is the radius.so 2R is twice the radius (a.k.a. The Diameter)That leaves you withCircumference=Diameter*PiThe circumference can be found by multiplying the diameter by pi, and the diameter can be found by dividing the circumference by pi.

Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.

The letter or character used to represent the ratio of the circumference to the diameter of a circle is the Greek lower case letter π, called "pi."

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.

what z radius ratio

That depends what you mean by "size". Diameter: 0.38 times the diameter of Earth. Radius: same number, since the radius is half the diameter. Volume: the ratio of the diameters cubed. Mass: 0.055 times Earth's mass.

The diameter is two times the radius. a diameter of 8 units is 16 units of radius. Since area is proportional to radius squared ( pi x radius squared) then the area ratio of the bigger circl is (16/2) squared or 8 x 8 = 64 times greater.

The force represents the ratio between the rotational work and the radius of rotation.

The ratio (for the covalent radius of the atom) is cca. 1/25000.

π is the ratio between the diameter and the circumference of a circle so the formula would be : Circumference = π x Diameter or alternatively (since the radius is half the diameter) Circumference = 2π x Radius.

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).

No, the circumference divided by the radius will always be pi for a circle.
