Why is it 4 3 for volume of a sphere

Answered By: Martin Rodriguez Date: created: Sep 03 2021

Why is the volume of a sphere 43πr3? I learned that the volume of a sphere is 43πr3, but why? The π kind of makes sense because its round like a circle, and the r3 because it’s 3-D, but 43 is so random!

Why is a sphere 4 pi r 2

Answered By: Gregory Lopez Date: created: Sep 19 2021

Both these “annuli” have the same area 2πrΔz. As this is true for any such plate it follows that the total area of the sphere Sr is the same as the total area of Z, namely 4πr2.

Does a sphere have a top or bottom

Answered By: Carlos Foster Date: created: Apr 12 2021

In a sense (let’s assume the world is a sphere) a sphere has no top or bottom unless you draw a smily on it. … If a sphere is spinning it would be natural to think of either end of the rotational axis (where it coincides with a surface) to be the top or bottom.

Why is volume of sphere

Answered By: Colin Sanchez Date: created: May 01 2021

Volume of a sphere = 4/3 πr3 The difference between the two shapes is that a circle is a two-dimensional shape and sphere is a three-dimensional shape which is the reason that we can measure Volume and area of a Sphere.
