If the radius(r) of the circle is 15mm then,
circumference of the circle = 2πr = 2*22/7*15/1000cm=....now you can solve on your own!

r=1.5mm
circumference=2πr
circumference= 2×(22/7)×1.5
circumference= 66/7
circumference=9.428mm
radius =7.2cm
circumference=2πr
circumference= 2×(22/7)×7.2
circumference=316.8 /7
circumference=45.257mm
circumference=2πr
