What is the radius of one sphere?

The radius is half the diameter, so use the formula r = D/2. This is identical to the method used for calculating the radius of a circle from its diameter. If you have a sphere with a diameter of 16 cm, find the radius by dividing 16/2 to get 8 cm. If the diameter is 42, then the radius is 21.

What is the radius of a sphere surface area?

Given diameter: r = d / 2 , Given area: r = √[A / (4 * π)] , Given volume: r = ³√[3 * V / (4 * π)] , Given surface to volume ratio: r = 3 / (A/V) .

Does sphere have radius?

This distance r is the radius of the ball, which is made up from all points with a distance less than (or, for a closed ball, less than or equal to) r from the given point, which is the center of the mathematical ball. These are also referred to as the radius and center of the sphere, respectively….

Sphere

What is the diagonal of a sphere?

That diagonal has length Sqrt[N]. The part of the diagonal going through the sphere S has length 1 because that is the diameter of S. Of the part that is left over, half of it is in the central sphere, and in fact forms the radius of that central sphere. So the central sphere has radius (Sqrt[N]-1)/2.

How many sides has a sphere?

Cones, spheres, and cylinders do not have any edges because they do not have any flat sides. The place where two or more edges meet is called a vertex. A vertex is like a corner.

What is radius and diameter?

The diameter is a straight line that passes through the center of the circle. The radius is half of the diameter. It starts from a point on the circle, and ends at the center of the circle.

How do I find the radius of a circle from the area?

To find the radius, divide the area by pi, then take the square root.

How do you find the radius of a sphere in math?

The formula used to calculate the sphere radius is: r = ∛((3/4) · V / π) Symbols. r = Sphere radius; V = Sphere volume; π = Pi = 3.14159… Volume of Sphere. Enter the volume contained within a sphere. Radius of Sphere. This is the radius of a sphere that corresponds to the specified volume.

What is radius in physics?

The radius is the distance between the centre and any point on the surface of a sphere. This is the total area of the surface of a sphere with the specified radius.

What is the circumference of a sphere equal to?

As with circles, the circumference of a sphere is equal to π times the diameter. Since the diameter is twice the radius, we can also say that the circumference is twice the radius times π. V = (4/3)πr3. The volume of a sphere is the radius cubed (times itself twice), times π, times 4/3.

What is the formula to find the volume of a sphere?

1 D = 2r. As with circles, the diameter of a sphere is twice the radius. 2 C = πD or 2πr. As with circles, the circumference of a sphere is equal to π times the diameter. 3 V = (4/3)πr3. The volume of a sphere is the radius cubed (times itself twice), times π, times 4/3. 4 A = 4πr2.
