It is .25 mm that is the larger diameter
millimeterANS 2 -1 millimeter is approximately 1/25 of an inch.
circumference of a circle = 2*pi*radius or diameter*pi
So I assume 25 millimetres is the diameter. Therefore the Cylinder (assumption) volume is pi x r^2 x h, i.e. 3.14159 x 12.5 x 12.5 x 100, giving 49087.343 millimetres cubed. this gives you 49.087343 millilitres.
1 dollar and 25 cents to be exact.
The pipe will have an outside diameter of 1.5+.25+.25 = 2". A pipe with an outside diameter of 2" has an outside circumference of 2"*Pi. 2"*3.142 ~= 6.284" or about 6 1/4"
Radius = Diameter / 2 = 25 cm.
This question makes no sense. 2 millimetres is larger than 1 millimetre, but 2.3 millimetres is larger than 2 millimetres and so on - all the way up the number line.
Circle circumference = 2 pi d = 2 (3.14 ) 25 = 157
Radius = 1/2 (diameter) = 25 inches.
Radius = Diameter/2 = 25 cm.
Radius = 1/2 of the diameter = 12.5 cm.
If the diameter is 25 mm then the circumference is 78.54 mm.
