## How do you find a spheres rate?

Check out this radius of a sphere calculator and answer these questions….What’s the radius of a sphere formula?

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

## How do you find the volume of a sphere given the circumference?

Sphere Formulas in terms of radius r:

1. Volume of a sphere: V = (4/3)πr.
2. Circumference of a sphere: C = 2πr.
3. Surface area of a sphere: A = 4πr.

## How do you find the rate of change of a radius?

The rate of change of the radius dr/dt = . 75 in/min because the radius is increasing with respect to time. hence, the volume is increasing at a rate of 75π cu in/min when the radius has a length of 5 inches.

## What is the area of the sphere?

4πr²
Surface Area of Sphere = 4πr², where r is the radius of sphere. A sphere is a solid figure bounded by a curved surface such that every point on the surface is the same distance from the centre.

## What is the diameter of one sphere?

There are four main formulas for a sphere which include sphere diameter formula, sphere surface area, and sphere volume….Formulas of a Sphere.

Sphere Formulas
Diameter of a Sphere D = 2 r
Surface Area of a Sphere A = 4 π r2
Volume of a Sphere V = (4 ⁄ 3) π r3

## What is the rate of change of volume?

The volume rate of change is the indicator that shows whether or not a volume trend is developing in either an up or down direction. You may be familiar with price rate of change (discussed here), which shows an investor the rate of change measured by the issue’s closing price.

## What is the formula of TSA of sphere?

And the formula for the surface area of a sphere of radius R is 4*Pi*R2.
