For example, for latitudes 12 and 13 degrees north, we have an area of 2πr(sin(13 ∘) − sin(12 ∘)) = 2πr(0.2249 − 0.2079) = 0.034 × πr. The reason for the r ′ = rcos(θ) is the following. The circle at a latitude of θ (where angle is computed from the equator), makes an angle ... birthday thanksgiving to god
