W(t)W, left parenthesis, t, right parenthesis models the daily water level (in \text{cm}cmstart text, c, m, end text) at a pond in Arizona, ttt days after the hottest day of the year. Here, ttt is entered in radians. W(t) = 15\cos\left(\dfrac{2\pi}{365}t\righ t) + 43W(t)=15cos( 365 2π t)+43W, left parenthesis, t, right parenthesis, equals, 15, cosine, left parenthesis, start fraction, 2, pi, divided by, 365, end fraction, t, right parenthesis, plus, 43 What is the first time after the hottest day of the year that the water level is 30 \text{ cm}30 cm30, start text, space, c, m, end text? Round your final answer to the nearest whole day.
