May 17, 2010 -- A new study shows eating processed red meat -- such as hot dogs, bacon, sausage, and cold cuts -- is linked to increased risks of heart disease and diabetes.But the study, published in Circulation, shows no such link for unprocessed red meat.ating one serving a day of processed meat -- or the equivalent of a single hot dog or two slices of salami -- was associated with a 42% increased risk for heart disease and a 19% increased risk for diabetes in the study, conducted by researchers from the Harvard School of Public Health.
A central angle is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B. The central angle is subtended by an arc between those two points, and the arc length is the central angle (measured in radians) times the radius.
The centre of a circle is the point in the very middle. The radius of a circle is a line from the centre of the circle to a point on the side. All points on the edge of the circle are at the same distance from the centre. In other words, the radius is the same length all the way around the circle. Mathematicians use the letter r for the length of a circle's radius.
