The volume of a cylinder that is 30mm in diameter and 700mm high is 494,800.84mm3
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.
Area = pi*152 square mm
Area of the circle: pi*152 = 706.858 square mm to 3 decimal places
In terms of length, 30mm is greater than 3cm. This is because 1cm is equal to 10mm. Therefore, 3cm is equivalent to 30mm.

radius = 60/2 = 30mm
A 30mm diameter would be roughly the size of a US half-dollar coin, which has a diameter of 30.61mm. It is slightly smaller than the diameter of a standard ping pong ball (40mm) and about half the diameter of a standard CD (120mm). In terms of everyday objects, it is similar in size to a large marble or a typical wine cork.
Area = pi*152 square mm
The radius is half the diameter 15mm because the raduis is half the diameter so 30mm divided by 2mm it would be 15mm
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
King George II Halfpennies varied in size from 28 to 30mm in diameter.
Asking what the calibre is is the same as asking how many inches... In this case, the bore diameter would be 1.1811 cal.

] [ on my screen the distance between those two brackets is 30mm - but depends on screen size I guess - mine is 430mm diagonally.
Yes, a VERY large one known as the GAU-8. It fires a 30mm diameter bullet.
