WebDec 6, 2024 · Kelvin’s prediction of a cosmic heat death is easy to understand. We need look no further than the sun, which is busily pouring out heat lost to the cold depths of space at the prodigious rate of about 10 20 megawatts. That will continue so long as the sun has reserves of nuclear fuel. But sooner or later the fuel will run out and the sun ... WebFeb 17, 2016 · A. In order to calculate a circle’s circumference, we need to know either its diameter or its radius. We then use the appropriate value in this equation: C = 2 π r (where “ r ” represents radius, of course). Ex. Find the circumference of this circle: r = 10 units 2 = 5 units. C = 2 π r = 2 π × 5 = 10 π units. Q.
