Answer:
A=777.54
Step-by-step explanation:
What you do is use the formula which is
a=2pirh+2pir^2.
The radius is half the diameter and the diameter is 15 so you take 15 and divide it by 2 to get 7.5.
The height is 9 m.
A=2(3.14)(7.5)(9)+2(3.14)(7.5)^2=777.54 m.

Hi there!
f(x) = x + 5
1. y = x + 5
Switch places from x and y.
2. x = y + 5
Subtract 5.
3. x - 5 = y
Switch sides.
4. y = x – 5
Now we've found our answer.
~ Hope this helps you!
