Question

dy/dx
Find
for x2+y2+z2=a2

​

Answer 1

The equation,

${x}^{2} + {y}^{2} + {z}^{2} = {a}^{2}$

represents a 3D sphere with centre at the origin. Here a is the radius of the sphere.

Volume of sphere with given radius a,

$= \frac{4}{3} \pi {a}^{3}$

This should yield the volume of the sphere.
