Answer:
Step-by-step explanation:
I assume you mean :
Use the formula where and are the lower and upper bounds and is the equation of the polar curve.
Since the graph is symmetrical about the line , let the bounds of integration be to find half the area of the curve, and then find twice of that area:
Thus, the area of the curve is 41π square units. See below for a graph of the curve and its shaded area.
