Question

Find by double integration, the centre of gravity of the area of the cardioid
r=a (1 + cos 6).
​

Answer 1

Answer:

Hyy

Step-by-step explanation:

Find the area inside the cardioid r = 1 + cos θ. Answer: The cardioid is so-named because it is heart-shaped. Using radial stripes, the limits of integration are (inner) r from 0 to 1 + cos θ; (outer) θ from 0 to 2π.
