Chapter 1, Problem 2CR

To determine

To State: Number of red points from point O at 1cm distance.

Answer to Problem 2CR

Thus red points which are $1\text{cm}$ from point $O$ are 2 in numbers.

Explanation of Solution

Given information:

Radius of the circle =1cm

  

From the given figure there is a blue color circle whose radius is $1\text{cm}$ from the center point $O$

According to the definition of circle every distance from the center point of circle is a radius which is equal from every point from circle to its center point.

  

Hence from this it concludes that there are two points which are $1\text{cm}$ from center point $O$ of the circle.

Therefore, red points which are $1\text{cm}$ from point $O$ are 2 in numbers.
