Answer:
Step-by-step explanation:
We are to integrate the function

over the area enclosed by the circle

Convert into polar coordinates

x=rcost and y = rsint
Since the lines are x=0 and y=x we find that t varies from 0 to pi/4

Double integral will become now

(since variables are independent here)
Substitute for r and t
4 sin pi/4 -2 cospi/4
= 
Answer:
4.5 ft
Step-by-step explanation:
cos 68° = x / 12
x = 12 x cos 68° = 12 x 0.375 = 4.5 ft
