Answer:
(x,y) = (0,-8)
Step-by-step explanation:
We know that a point in polar coordinates is represented by
(r, θ)
Where r is the distance from the origin and θ is the angle.
Rectangular coordinates can be found by
x = r*cos(θ)
y = r*sin (θ)
x = r*cos(θ) = 8* cos (3π/2)
y = r*sin (θ) = 8 sin(3π/2)
x = 8* cos (3π/2) = 8*0 = 0
y = 8* sin (3π/2) = 8*(-1) = -8
(x,y) = (0,-8)

Step-by-step explanation:
Find pie for both circles
13 x pie = 40.8
6 x pie = 18.8
40.8 - 18.8 = 22
