circle 1 circumference = 2 * 3.14 * 10
= 62.8 CM
circle 2 circumference = 2*3.14 * 12
= 75.36 CM
circle 3 circumference = 2*3.14*18
= 113.04 CM
total circumference = 62.8+75.36+113.04
= 251.2 CM
let the radius be x , so the diameter is 2x
251.2 = 2*X*3.14
251.2=6.28X
X= 251.2/6.28
=40
2x = 80 cm = Diameter
