We Need more info. which engine.. Make/model/year, and which diameter Bore, main/rod journals?
Outer jaws are used. Inner jaws will be use to find the inner dia of the cylindrical vessel.
if you mean a cylinder with a hole through it like a pipe or tube, then it's pi x (Od2 - id2)/4 x h Od = outer diameter id = inner diameter
Consider going across the width of the pipe: Outer diameter = Thickness + Inner diameter + Thickness so 2*Thickness = Outer diameter - Inner diameter = 2.5 - 2.1 = 0.4 inches and therefore, Thickness = 0.2 inches.

Remembering that there is an inner core inside the outer core - the radius of the outer core/mantle boundary is about 3,400 km. (the diameter is twice the radius).
by using a caliperhttp://www.technologystudent.com/equip1/vernier3.htm
Outer radius minus inner radius Subtract the inside diameter from the outside diameter, then divide the difference by 2.
For the inner area, multiply...the inner diameter x pi x the length of the pipe.For the outer area, multiply...the outer diameter x pi x the length of the pipe.
the thickness of the outer core is 2250 km.
INNER PLANETS - SmallEarth is the largest of the Inner Planets, with a diameter of 12,756 km (7,926 miles). Mercury is the smallest with a diameter of 4,878 km (3,031 miles)OUTER PLANETS - Huge!Jupiter, the largest planet, has a diameter of 142,984 km (88,846 miles). Neptune is the smallest of the Outer Planets with a diameter of 49,532 km (30,779 miles)
The heater hose for a 2004 F-150 Heritage is 21 inches long. End number one has an inner diameter of 0.78 inches and an outer diameter of 1-inch. End number two has an inner diameter of 0.75 inches and an outer diameter of 0.78 inches.
Depends on if the 10" is inner or outer diameter, and the length of the pipe.
