Question

A line touches a circle of radius 4 cm. Another line is drawn which is tangent to the circle. If the two lines are parallel then distance between them is

• A. $4cm$
• B. $6cm$
• C. $7cm$
• D. $8cm$

Answer 1

The correct option is D $8cm$

Distance of tangent from the centre$=$Radius$=2cm.$
Therefore distance of AB from centre$=$Distance of CD from centre$=4cm.$
Distance between AB and CD$=2\times$Radius $=8cm$
