Convert from rectangular to polar coordinates: note: choose rr and θθ such that rr is nonnegative and 0≤θ<2π0≤θ<2π (a)(9,0)⇒(r,θ)(a)(9,0)⇒(r,θ)( 9 equation editorequation editor , tan(0) equation editorequation editor ) (b)(18,183√)⇒(r,θ)(b)(18,183)⇒(r,θ) ( 20.7846 equation editorequation editor , tan(18/sqrt(3)/18) equation editorequation editor ) (c)(−5,5)⇒(r,θ)(c)(−5,5)⇒(r,θ)( 10 equation editorequation editor , equation editorequation editor ) (d)(−1,3‾√)⇒(r,θ)(d)(−1,3)⇒(r,θ)( 4 equation editorequation editor ,

Step-by-step explanation:

Convert rectangle (x , y) to polar coordinates ( r , θ)

a) converts (9, 0) to polar coordinates  ( r , θ)

b) Convert to polar coordinates ( r, θ)

c)  converts (-5, 5) to polar coordinates  ( r , θ)

d)  converts (-1, √3) to polar coordinates  ( r , θ)

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
