Question

find the volume of sphere x2+y2+z2=a2​

Answer 1

Answer:

See below.

Step-by-step explanation:

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.

Answer 2

Answer:

Step-by-step explanation:

given that,

f = x^2+y^2+z^2=a^... let this is eqn(1)

volume of sphere is V=(4/3)πa^3 = ¢

we know that,

F=f+¢
