Question

What is the equation of the sphere with unit radius having centre at the origin ?

IIT - JEE Question.

Answer 1

Answer:

= 1

Step-by-step explanation:

We know that, the standard equation of the sphere, whose centre at (x₁ , y₁ , z₁) and radius is r, is

   (x - x₁)² + (y - y₁)² + (z - z₁)² => x² + y² + z² = 1

But given that, centre (0, 0, 0) and radius = 1

   ∴ Required equation of sphere is

( x - 0 )² + ( y - 0 )² + ( z - 0 )² = (1)²

       => x² + y² + z² = 1

Good luck !!
