81. During a rainfall, the depth of water in a rain gauge increases at a rate modeled by R(t) = 0.5 + tcos 80 where t is the time in hours since the start of the rainfall and R(t) is measured in centimeters per hour. Ho much did the depth of water in the rain gauge increase from t = 0 to t = 3 hours? (A) 1.233 cm (В) 1.466 ст (С) 1.966 ст (D) 5.401 cm
