what the relationship between the diameter and radius?

First, note the definition of radius and diameter. The radius is one-half the diameter or the diameter is twice the length of the radius. Next, multiply the radius by 2 to get 6. The answer is 6.

The diameter of a circle is D=10 inches D = 10 inches . Therefore, the radius of the circle is 5 inches . Therefore, the circumference of the circle is approximately 31.41 inches .

The main difference between Diameter and Width is that the Diameter is a straight line segment that passes through the center of a circle and Width is a measured dimension of an object. ... In more modern usage, the length of a diameter is also called the diameter.

Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.

Covalent Radius The distance between two nuclei will give the diameter of an atom, but you want the radius which is half the diameter. Covalent radii will increase in the same pattern as atomic radii. The reason for this trend is that the bigger the radii, the further the distance between the two nuclei.

The area formula is πr². If the area is given as 4π, so in this case πr² = 4π. That means the square of the radius (r) is 4, and the radius is 2. So the diameter is 4, and the circumference (πd) is 4π.

Finding the Diameter or Radius The circumference of a circle is equal to pi times the diameter. The diameter is two times the radius, so the equation for the circumference of a circle using the radius is two times pi times the radius.

The circumference is the total length around the circle. It's equal to (pi x diameter) OR (2 x pi x radius). The area of the circle is the surface area enclosed by the circle, which is equal to pi x (radius ^ 2).

Pi (Ratio of the Circumference of a Circle to Its Diameter) Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

If the radius is r, then the circumference is 2πr. If the radius r is tripled it becomes 3r. The circumference will then be 2π(3r) = 3(2πr). Thus the circumference gets tripled also, when the radius is tripled.

Using the Radius First, double the radius to get the diameter (radius x 2, or radius + radius). One you have the diameter, you can use the equation C = πd. If you want to know the circumference of a cookie that has a radius of 2 inches, for instance, start by doubling the radius to get the diameter: 2 x 2 = 4.

The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle. ... When we divide the circumference by the diameter we get 3.141592654...

The radius and the height are perpendicular to one another, but there is no particular relationship between their respective lengths. There can be a very long skinny cylinder or a very squat and fat cylinder. Edit: on further reflection, height and radius are both related to volume.

In fact, the average speed and the radius of the circle are directly proportional. A twofold increase in radius corresponds to a twofold increase in speed; a threefold increase in radius corresponds to a three--fold increase in speed; and so on.

The diameter, like in a normal circle, is just twice the radius. If given the perimeter: The perimeter of a semicircle will be one half the circumference of its original circle, πd , plus its diameter d .

First, double the radius to get the diameter (radius x 2, or radius + radius). One you have the diameter, you can use the equation C = πd.

The area of a circle is equal to the square of its radius times pi. The circumference of a circle is equal to the diameter times pi. ... So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up.
