recession is obviously severe, its output cost so far has been much smaller than that of the Great Depression. Stijn Claessens is an Assistant Director and M. Ayhan Kose is a
an O-ring, a good fit is critical. O-rings are measured in millimetres. Place the O-ring on a clean, flat, level surface. Determine the inside diameter. Use a ruler to measure from one inner edge to another. To measure the outside diameter, use a ruler to measure from one outer corner of the O-ring to the other outer corner. Measure cross section. Place the O-ring into a vernier calliper. Lightly clamp the jaws of the calliper onto the O-ring, but do not compress it. Record the thickness of the ring (the cross section). If you only have 2 of the O-ring diameters then you can determine the third diameter with the following equations: Measurements: Outside Diameter (OD) = Inside Diameter + (2 x Cross Section). Inside Diameter (ID) = OD - (2 x CS). Cross Section (CS) = OD - ID, Ã· 2. If the o-ring is cut, measure the cross section (thickness) of the O-ring and the length. Converting Length to Inside Diameter: Length Ã· 3.142 = circumference. Circumference - CS = ID.
So, the candy they say is in the shape of circular disc and they tell us that the diameter is 16 millimeters. If I draw a line across the circle, that goes through the center. The length of the line all the way across the circle through the center is 16 millimeters. The Diameter here is 16 millimeters. And they want us to figure out the area of the surface of the candy. Essentially the area of this circle. When we think about area, we know that the area of the circle is pi times the radius of the circle square. They gave us the diameter, what is the radius? well, you might remember that the radius is half of the diameter. Distance from the center of the circle to the outside, to the boundary of the circle.
