Question

what is the distance between two parallel tangent of a circle having radius 4.5cm?justify your answer ​

Answer 1

Final Answer :9 cm  

1) We know : 

Distance between any two parallel tangents in a circle is equal to measure of a Diameter . 

For example, Look at Pic;

Distance between any parallel tangents = 2*r=2*4.5=9 cm 

This can be seen as since tangents are parallel and both touches the circle at one point .

Hence, we can say a length of Diameter will fulfill the perpendicular gap between them .

So, Distance between two parallel tangents will be twice of length of radius or Diameter only.

Answer 2

The distance is 9 cm. Because they are between two radii and are parallel. See the diagram and you will understand
