Question

sphere and cylinder are having same height and same radius .then find how many cylinders can be formed by melting of sphere​

Answer 1

Answer:

Step-by-step explanation: no of cylinders from sphere=volume of sphere/volume of cylinder

=

$4/3\pi r^3/ \pi r^2h\\=4/3\pi r^3/ \pi r^3\\. (Height =radius)\\\\\\=4/3$

Answer 2

Answer:

Step-by-step explanation:

Let the radius of the cylinder be r and the height also be r given that the radius and the height are equal.

The volume of a sphere = 4/3pier^3

The volume of a cylinder = pie × r^2 × h

The volume of the cylinder = pie × r^3

If the sphere is cast into cylinders how many cylinders can be formed?

We divide the two to get :

(4/3pie × r^3) / (pie × r^3)

This equals to 4/3

Which is 1.33

Which is approximately 1 cylinder.
