**How do you find the area of one petal of r Socratic.org**

9/07/2009 · Best Answer: You can solve this by solving double integral with the curves as limits in polar coordinates. The limits of integration for the radial coordinate are : 1/2 ≤ r ≤ 1 - sin(θ) There is some region, in which inequality above cannot be satisfied, because the first curve, which is not really a... 5/12/2012 · Best Answer: The angle will be from 0 to pi/12 If you plot the graph very carefully with theta extends from 0 to pi/12 you have exactly one loop Therefore the area of one loop is of 1/2 integral (sin(12theta))^2 d theta with theta =0 to pi/12 ==> pi/48
