Question

Radius of a circle with centre O is 8cm. Points A and B are such that AO= 6cm and BO =10cm state which of the points A and B is in the interior and exterior of the circle.

• A. Point B is in interior and point A is in exterior of the circle.
• B. Point A is in interior and point B is in interior of the circle.
• C. Point A is in interior and point B is in exterior of the circle.
• D. Point A is in exterior and point B is in exterior of the circle.

Answer 1

The correct option is C Point A is in interior and point B is in exterior of the circle.

Let radius $=r=8cm$.

Since $OA=6cm<r\Rightarrow$ A lies inside the circle

and $OB=8cm>r\Rightarrow$ B lies outside the circle

So option C is the right answer.
