OD. 22 Find the area inside the oval limaçon r= 8 +3 cos e Find the area of the region inside the circler= - 2 sin and outside the circle r= 1. Find the length of the parabolic segment r= 1+ cos o ososa The area inside the oval limaçon is (Type an exact answer, using a as needed.) The area of the region is I (Type an exact answer, using a as needed.) The length is (Type an exact answer, using radicals as needed.) Question 4 Question 5 Question 3

Answer 1

Q1) to convert rectangular coordinate s into polar form we write y=rsin(theta),x=rcos(theta)

So here y=9

Therefore rsin(theta)=9

So r=9/sin(theta)

r=9cosec(thata)
