Answer 1

Answer:

3 centimetre is the answer..... please also follow the stepwise explanation.

Step-by-step explanation:

the radius of circle is 5cm . let it be the hypotenuse . let the height be bc =4cm.

therefore by Pythagoras theorem

${5}^{2} = {4}^{2} + ac {}^{2}$

$25 - 16 = ac {}^{2}$

$\sqrt{9} = ac$

$ac = 3cm$
