Answer:
c) r= 2sin θ
Step-by-step explanation:
Remember, 
therefore,
Also y= rsin θ
Given rectangular equation:
x²+y²+ 2y
r²= 2(rsin θ)
r²= 2rsin θ
dividing r from both sides
r= 2sin θ
Answer:
6 in
Step-by-step explanation:
To find the height, just divide the volume by the base area
Im pretty sure it would be (5, 40)!
the equation is y=8x :-)
You just have to add 30 to the total of seats. Good luck.

HOPE THIS HELPS!!!
