The radius of a coin with diameter of 45 mm is : 45/2 = 22.5mm The circumference of a coin with diameter of 45 mm is 45*pi = 141,372mm rounded to 3 decimal places
A .222 caliber bullet has a diameter of 5.56mm.
The diamater of a 9mm parabellum bullet is 9.03 millimeters, or .356 of an inch.
As far as diameter, there is very little difference. A .357 is .358 in diameter and a 9mm is .356 in diameter.
about 11 mm in dia.
I think you mean .32 caliber, not mm. It means that the gun fires a bullet that is about 32/100ths of an inch in diameter. A 9mm fires a bullet 9mm in diameter- or about .35 inches in diameter. A 32 mm bullet would be about the size of big (D cell) flashlight battery!
.284
A 22 caliber bullet is 22/100 inches in diameter. A 7.62 mm bullet is 30 caliber or 30/100 inches in diameter there is no such thing as a 7.62 caliber bullet
A bullet with a diameter of approximately 9mm. Not all 9mm projectiles are exactly 9mm in diameter - the 9x19 Parabellum/Luger has a diameter of 9mm, while the 9x18 Makarov has a diameter of 9.27mm, the 9x23 Steyr has a diameter of 9.03mm, etc.
Yes they is a differnent. When people say "38" they usually mean .38 special, which is a revolver cartridge. .380 ACP is a semi-automatic cartridge. The bullet in a .380 cartridge, even though it's called .380, is actually very slightly smaller in diameter, and lighter than the bullet in a .38 cartridge. The .38 bullet is 0.357 inches in diameter while the .380 is 0.350 inches in diameter. Technically, the .380 cartridge is considered part of the 9 mm class of bullets. [9 mm x 19 mm = 9 mm Luger or 9 mm Parabellum, 9 mm x 18 mm = 9 mm Tokarov, and 9 mm x 17 mm = .380 ACP]
No such thing. It is a typo. A 45 mm pistol would fire a bullet larger than a golf ball. I think you are looking for a .45 CALIBER pistol. That is a handgun that fires a bullet about 45/100ths of an inch in diameter. Perhaps the two best known are the 45 Colt Peacemaker type revolver of cowboy fame, and the 1911A1 .45 Automatic Pistol, used by the US Army.
