Answer:

27.3cm

Step-by-step explanation:

area = πr

but, πr - (area of semi circles done by the lines )

so, line 1 - a

line 2 - b

line 3 - c

area of a = πr

= 22/7× 6

= 132/7cm²

area of b = πr

=22/7×6

= 132/7 cm²

area of c =πr

= 22/7×14

= 22×2

= 44

now, πr - (132/7 + 132/7 + 44) = 0

πr - (602/7)= 0

πr = 86

r = 86 × 7/22

r = 43 × 7/11

r= 27.3 cm..
