The cross-sectional area of a tube is equal to the area of the outer circle minus the area of the bore, so using the formula for area of a circle, we can do the following.
A = pi*(42/2)2-pi*(26/2)2 = 272 pi, A = 854.513 mm2
42mm
3-9x42 typically refers to a type of rifle scope with a magnification range of 3 to 9 times and a 42mm objective lens diameter. This scope allows users to adjust the magnification for different shooting distances, making it versatile for various hunting or shooting scenarios. The 42mm lens diameter helps gather light, improving visibility in low-light conditions.
To compare 42MM and 10CM, we need to convert both measurements to the same unit. Since 1CM is equal to 10MM, 10CM is equivalent to 100MM. Therefore, 42MM is indeed larger than 10CM.
42/10 = 4.2 mm/10

42mm is a standard socket. If you mean "what SAE socket fits," none of them do. BTW, what are you trying to get off that's got a nut that big on it?
Stock bore is 42mm.
42/10 = 4.2 mm/10
The 12x42 binoculars have a magnification power of 12x and a lens diameter of 42mm. This means they can make objects appear 12 times closer and have a wider field of view. They are suitable for activities like birdwatching, hunting, and stargazing.
For birdwatching, it is recommended to use binoculars with a magnification power of 8x to 10x and an objective lens diameter of 42mm to 50mm. These specifications provide a good balance of magnification and light-gathering ability for observing birds in various lighting conditions.
