The barrel is probably much like a cylinder. All surface area is the lateral area+the area of the base(s).
In this case:
SA=(d)("pi")(h)+(2)("pi")(r2)
SA is surface area
d is diameter of the circle base
h is the height
r is the radius of the base
What you are doing with this equation is figuring out the circumference x the height, so you get the area of the tall part. Then you take the area of one of the bases and multiply it by 2.

How do you find the surface area of a parallelogram?
The formula to find the surface area of a parallelogram is Base*Height.
What is the surface area formula for a dodecahedron?
the surface area formula is difficult to understand. there is another way to do it.you find the area of one pentagon. then u multiply it by the number of faces which is 12.
The surface area formula for a right cone is the same as the surface area formula for an oblique cone?
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
What is the formula to find the surface area of a rectangle?
Length X Width.
What is the surface area formula for a rectangular prism?
A= 2(wh+lw+lh) where w = width h = height and l = length When trying to find the surface area of something, it is important to try to remember the specific formula. The formula for the surface area of a rectangular prism is A=2(wl+hl+hw).
