Question

Write the standard equation of the circle with given center and radius.

Center: (0, 0)

Radius: √ 11 (square root of 11)

Answer 1

x² + y² = 11

Explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( where r is the radius )

Here r =
`√(11)` ⇒ r² = (
`√(11)` )² = 11, thus

x² + y² = 11 ← equation of circle
