## General Equation of Sphere

A sphere is a three-dimensional object with all points on its surface equidistant from a fixed point called the center. The equation of a sphere with center (x, y, z) and radius r is

x2 + y2 + z2 = r2

## Deriving the Equation of a Sphere

The equation of a sphere is:

x2 + y2 + z2 = r2

Where r is the radius of the sphere.

## Volume of a Sphere:

4/3*pi*r^3

## Surface Area of a Sphere:

The surface area of a sphere is the total area that the surface of a sphere occupies. To find the surface area of a sphere, you need to know the radius of the sphere. The surface area of a sphere is equal to 4πr2.

TORONTO – Ontario’s governing Liberals say they’re committed to creating a made-in-Ontario pension plan, but they’re not sure how it will work.

Finance Minister Charles Sousa says the plan will be designed to supplement the Canada Pension Plan, which he says is not sustainable in the long term.

Sousa says the government is still working on the details of the plan, but it will be voluntary and designed to help people who don’t have a workplace pension.

He says the government is also looking at ways to help businesses that offer their employees pension plans.

The Liberals say they plan to introduce legislation to create the Ontario pension plan in the fall.

The average lifespan of a hummingbird is around 5 years.

## Important Elements of a Sphere

A sphere is a three-dimensional object that has a curved surface and is round. It has no edges or corners. Some of the important elements of a sphere are its diameter, circumference, and surface area.

## Properties of a Sphere

A sphere is a three-dimensional, closed shape that is round and has no ends. It is the most perfectly round shape possible. A sphere has a radius and a diameter. The radius is the distance from the center of the sphere to its edge, and the diameter is the distance from one side of the sphere to the other. A sphere also has a surface area and a volume. The surface area is the total area of the sphere’s surface, and the volume is the amount of space inside the sphere.
