How to find the distance of the root from the origin?

1. What is the formula for distance from the origin?
2. What is the distance between the origin and − 3 − 4 )?
3. What is the distance of a from origin?

What is the formula for distance from the origin?

According to the distance formula, this is √(x−0)2+(y−0)2=√x2+y2. A point (x,y) is at a distance r from the origin if and only if √x2+y2=r, or, if we square both sides: x2+y2=r2.

What is the distance between the origin and − 3 − 4 )?

The coordinate point of the origin is (0, 0) . The given point is (3, −4) . Hence, the distance is 5 units .

What is the distance of a from origin?

Answer: Distance of a point P(x, y) from the origin is given by d(0,P) = √ x2 + y2.
