Surface Area of A Cylinder. 
As=2(3.14)rh+2(3.14)r^2
Radius: 6in
Height: 9 in 
Plug it in: 
2(3.14)(6)(9)+2(3.14)(6^2)
6.28(54)+6.28(36)
339.12+226.08= 565.2
Therefore, it will take about 565.2in^2 of wrapping paper to cover the whole present.

Answer:
8
Step-by-step explanation:
( 12 + 3m ) / 2 = 18
12 + 3m = 18 x 2
12 + 3m = 36
3m = 36 - 12
3m = 24
m = 24 / 3
m = 8
