Question

find the equation of circle with Centre as origin and radius equal to a unit​

Answer 1

Answer:

Equation of the circle with centre as origin and radius of 1 unit x² + y² = 1

Step-by-step explanation:

We know that,

equation of a circle

=> (x - a)² + (y - b)² = r²

here,

• r = radius of the circle
• (a, b) = center of the circle

In the question,

• a = 0, and b = 0 (as center is the origin and origin = (0, 0))
• r = 1 unit

=> (x - 0)² + (y - 0)² = 1

=> x² + y² =  1

Therefore, the required equation is x² + y² = 1
