Answer:
make circle then make new one in the bigger one
then make a chord of bigger circle which touches the smaller one
the make radius of smaller circle on chord
then u see in figure two right angle triangle
radius of smaller circle divide chord into two equal part
by the use of pythagoras theorem = h2 = b2+p2
(5)power2=b2+3power2
25=b2+9
b=4
chord =2 *4=8
