We have

and

so the equation is indeed exact. So we want to find a function
such that


Integrating both sides of the first equation wrt
gives

Differentiating both sides wrt
gives

So we have

or

Answer:
1 13/15
Step-by-step explanation:
3−1=2
10/15−12/15=−2/15
2−2/15=1 13/15
The lateral area is the area around, the bases are the circles so the lateral area is the area of the rectangle
we just need the legnth of the rectangle which is the circumfernece of the circle
C=pid
d=12
C=12pi
area=lw
aera=12pi*15
area=180pi yd^2
