C = 2 * PI * R^2. divide both sides by 2 * PI to isolate R^2. C/ (2*PI) = R^2. Take square root of both sides to get R: sqrt (C/ (2*PI)) = R. Upvote • 0 Downvote. WebPnet = 3.375 W/m2 (2) We are given that the temperature on Earth increases by 0.25 oK for every additional Watt per square meter of net power. Thus, the tem-perature increase compared to pre-industrial times (i.e. the year 1700 A.D when the atmospheric CO2 concentration was at 270 ppm, imply-ing τ = 1) is temperature increase = 0.25oKm2/W ×P
