approximately 50mm internal diameter but you'll need to verify this with manufactures if you need it to be precise. For modelling purposes this will give you a rough idea.
Circumference of the circle: 63 times pi = 198 mm rounded to the nearest integer
63mm * 38mm * 198mm = 474,012mm3 or 474.012 cm3 if you prefer.

2 and 1/2 inches
The formula for the area of a triangle is A = 1/2 bh where b is the base length and h is the height. In this case, we know the area and height but not the base. We can still plug in the values we know and solve for the variable that we don't know. 63mm = 1/2 b(14mm) 63mm = b(7mm) 9 = b
ya there is
63mm because there is 10 mm in 1 cm
6.3cm = 63mm (there are 10 millimeters per centimeter).
6.3cm = 63mm (there are 10 millimeters per centimeter).
6.3cm = 63mm (there are 10 millimeters per centimeter).
cm x 10 = mm 6.3 x 10 = 63mm
1 centimetre = 10 millimetres. You now have all the information required to work out, for yourself, the answer to this and similar questions.
