30mm
3.4 cm
3.4 centimeters! oh yah! im right!
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
They are both the same because 30mm - 3cm
to convert 30mm into cm multiply the 30mm by 10. this is because there are 10mm to a cm.
30mm
3.4 cm
3 centimeters=30 millimeters
30mm 3 centimeters = 1.18110236 inches
3.4 centimeters! oh yah! im right!
10mm=1cm 20mm=2cm 30mm=3cm get it ? the list goes on .
1mm=0.1cm, therefore 30mm=3cm. 3cm is less than 5cm so 5cm is indeed greater than 30mm.
The diameter of any circle is twice the radius. Since the radius of this circle is 15mm, the diameter is 15mm*2=30mm. 30mm is also 3cm.
It is 297 mm.
About 3 centimeters (1.18 inches) in diameter... Radius 15mm Circumference of 9.42 cm, or 94.2 mm
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
