Hi i was going over this question from a lecture for polar coordinates we substitute Cos and sin right? I'm unsure how to go about it

3. The centroid of a region R in the my-plane having area A is the point with Cartesian
coordinates (E, 3]) given by i=i/medmdy, y=ifÃ©ydmdy. (The centroid would be the centre of mass if a plate in the shape of R was made
out of a uniform density material.) Find the centroid (LE, 37) of the circular sector given by the polar coordinate inequalâ€”
ities, 0\$TSR03 OSQSQO:
where 0 &lt; 90 &lt; 7r/ 2. You are given the area A = %R0290. Do the integrals in polar coordinates. Leave the answer as a pair of
Cartesian coordinates.
