How do you find the radius of a sphere if you know the area?
The surface area (S) of a sphere equals 4πr², where r is the radius. Using that equation to solve for r: r = √(S / 4π).
What is the radius of the sphere?
The Radius of a circle or sphere is equal to the Diameter divided by 2.
How do you find the radius of a sphere if you know the volume?
Answer: To find the radius of a sphere with the volume, we use the formula: r = (3V/4π)
How do we find the radius of a circle?
How to Find the Radius of a Circle?
- When the diameter is known, the formula is Radius = Diameter/ 2.
- When the circumference is known, the formula is Radius = Circumference/2π.
- When the area is known, the formula for the radius is Radius = ⎷(Area of the circle/π).
What is a formula for a sphere?
The formula for the volume of a sphere is V = 4/3 πr³.
How do you calculate the surface area of a sphere?
Also, assuming the same radius and diameter for a sphere, the surface area and volume of that sphere are returned. You may click on Clear Values to do another calculation. The formulas are as follows: area = PI * (radius) * (radius) or. area = PI * (diameter / 2) * (diameter / 2)
What is the formula to find the area of a circle?
The formulas are as follows: area = PI * (radius) * (radius) or. area = PI * (diameter / 2) * (diameter / 2)
How do you find the radius of a circle?
Enter the area contained within a circle. This is the radius of a circle that corresponds to the specified area. The radius is the distance between the centre and any point on the outer edge of a circle.
How to describe the area of a circle on a spherical manifold?
On a (flat) Euclidean plane, the area of a circle with a radius r can be described by the function A ( r) = π r 2. But how can one describe the area of the same circle on a spherical manifold? Assuming that the radius of the sphere is an Euclidean distance of d, how would A ( x) look?
