Question

if the length of tangent is 4 cm drawn from any point 10 cm away from the centre of circle then what will be the radius of the circle​

Answer 1

ANSWER :-

Length of tangent =x =4 cm

Length of tangent to centre of circle =y =10 cm

Radius of circle =z =?

By using Pythagoras theorem,

${y}^{2} = {x}^{2} + { radius \: of \: circle}^{2} \\ {10}^{2} = {4}^{2} + {z}^{2} \\ 100 = 16 + {z}^{2} \\ {z }^{2} = 100 - 16 \\ {z}^{2} = 84 \\ z = \sqrt{84} \\ z = 9.16515139 \: cm \: \: \: (answer)$

=> radius of circle= 9.165151139 cm
