Set up the double integral as efficiently as possible, in polar coordinates, that is used to find the area inside the cardioid r equals 1 plus cosine theta until it intersects with r equals 1 plus sine theta. Notice that because of symmetry, this can be doubled to find the area of the region.

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
