How much area of a sphere touches a flat surface?

Originally Answered: If two perfect spheres touched each other, how large are the touching areas? The area would be zero. IF the two were perfect spheres and didn’t deform due to touching or otherwise pressed against each other.

What are the parts needed to solve the surface area of a sphere?

The steps to calculate the surface area of a sphere is:

1. Step 1: Know the radius of the sphere.
2. Step 2: Take the square of the radius by multiplying it by itself.
3. Step 3: Multiply r2 by 4.
4. Step 4: Multiply the value of 4r2 by the approximate value of pi, that is, 3.14.
5. Step 5: At last, add the units to the final answer.

What do you call the surface area of a sphere?

The surface area of a sphere is defined as the region covered by its outer surface in three-dimensional space. A Sphere is a three-dimensional solid having a round shape, just like a circle. The formula of total surface area of a sphere in terms of pi (π) is given by: Surface area = 4 π r2 square units.

Is it possible to unfold a sphere?

The surface of a sphere and that of a flat surface have fundamentally different Gaussian curvatures which cause this to be impossible.

Which formula is the correct formula for calculating the area of a sphere?

A = 2 * π * r * 2 * r , A = 4 * π * r² , which is well-known area of a sphere formula.

What is a flattened sphere?

A spheroid, or ellipsoid, is a sphere flattened at the poles. The shape of an ellipse is defined by two radii. The longer radius is called the semimajor axis, and the shorter radius is called the semiminor axis.

How do you make a sphere flat?

2 Answers

1. Add a sphere to the scene via Shift + A > Mesh > Sphere.
2. Hit S to scale and then Y immediately to scale along the Y-Axis only.
3. Then drag the mouse in the right direction to adjust the flattening.

What is the surface area of a circle?

The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.

Can you find the surface area of sphere in any other way?

To find the surface area of a sphere, use the equation 4πr2, where r stands for the radius, which you will multiply by itself to square it. Then, multiply the squared radius by 4. For example, if the radius is 5, it would be 25 times 4, which equals 100.

What is the surface area of a sphere equal to?

Surface area of a sphere is equal to the areas of entire face surrounding it. Area of a Sphere- It is the amount of region covered by the surface of a sphere. Total Surface Area- It is the sum of total area of all the surfaces be it curved surface or flat surface.

What are the characteristics of sphere?

Important Facts: 1 A sphere is a symmetrical object 2 All the surface points of sphere are at equidistant from center 3 A sphere has only curved surface, no flat surface, no edges and no vertices.

What is the center of a sphere?

A sphere is three dimensional, geometrical shape, that has all its surface points equidistant from a common point. The distance between surface and the common point is the radius and the common point is called center of sphere.

What is the equation for the radius of a sphere?

In analytical geometry, if “r” is the radius, (x, y, z) is the locus of all points and (x 0, y 0, z 0) is the center of a sphere, then the equation of a sphere is given by: (x -x 0 ) 2 + (y – y 0 ) 2 + (z-z 0 ) 2 = r 2
