The volume of the sphere is: V=4πr3/3.

Then r=0,62 x (cubic root from V)

============================

Call the volume 'V'.

Call the radius 'R'.

The volume of a sphere is V = 4/3 (pi) R3 .

Multiply both sides of the formula by 3/4 :

3/4 V = (pi) R3

Divide each side by pi :

3V/4 pi = R3

Take the cube root of each side :

R = cube root of (3V/4 pi)

The first answer up above simplified this somewhat, by taking (3/4 pi)

out of the cube root, and you wind up with:

R = 0.62 times the cube root of ( V ) . (rounded)

How do you find the radius of a sphere based on the weight in pounds?

You need to know if the sphere is solid or hollow. You also need the "density" in terms of pounds weight per unit volume. Then Volume = Mass/Density And Radius = cuberoot[3*Vol/(4*pi)]


What is the mass of a sphere of radius 4cm?

To find the mass of a sphere, you need to know its density in addition to its volume. The volume ( V ) of a sphere can be calculated using the formula ( V = \frac{4}{3} \pi r^3 ). For a sphere with a radius of 4 cm, the volume would be approximately 268.08 cm³. If you provide the density of the material the sphere is made of, the mass can be calculated using the formula ( \text{mass} = \text{density} \times \text{volume} ).


If you know the diameter of a sphere you can find its radius true or false?

True. The radius is half the diameter.


What does the water level in a cylinder rise by when a sphere is submerged in it when I know the radius of the sphere and the radius of the cylinder?

Fist you've got to find the volume of the sphere, if the radius was 4cm then it would be...4/3*pi*r3=268cm V of cylinder= pi*r2*l (the radius for example is 8cm) 268=pi*64*l L=268/64pi =1.3cm


What is the formula for finding the radius of a circle when you have the volume?

If by circle you mean sphere, then the volume of a sphere is: 4/3 * pi * radius^3. If you already know the volume, then here's what you do: 1. Multiply the volume by 3/4. 2. Divide the volume by pi. 3. Take the cube root of both sides In other words, the formula for radius when volume is known is: ( ( Volume * 3 ) / ( 4 * pi ) ) ^ (1/3)

A solid rectangular block of metal 49cm by 44cm by 18cm is melted and formed into a solid sphere find the radius ofthe sphere?

To find the radius of the sphere, we need to know that the volume of the rectangular block is equal to the volume of the sphere. The volume of the rectangular block is 49 x 44 x 18 = 38,808 cm³. Equating this to the volume of a sphere (4/3πr³), we can solve for the radius which comes out to be approximately 22.18 cm.
