=
Note that the wall of the cylinder is in the shape of a rectangle. The width of the rectangle is the height of the cylinder. The length of the rectangle is the circumference of the circle base.
Surface area of cone is given by
where 
is the slanted height of the cone
SA of cone =
Hence total painted surface area is

Answer:17
Step-by-step explanation:Follow pemdas.
Start with parentheses which is (5+2) which gives you 7.
Now next in Pemdas is Exponents. SO do 2 to power of 2 which is 4 .Then do 3 to the power of 3 which is 27.Next add 4 to 27 which is 31.so now do 7 times 2 is 14.Then take 31 and subtarct it from 14 which gives you 17.
Look at pic to see clearly how it was solved and the steps. I color code it to show the steps.
