<p>i’m not askign u guys to do my homework but i’m pretty lost on this problem. Can anyone explain to me the problem or some type of hint?
Use a double integral and trigonometirc substitution, together with formula 64(i’ll write it down) to find the area of a cricile with radius 4.
formula = integral cos^2(u)=.5u+.25sin2u+c</p>
