work it out
i think its 144
Lateral surface :)
it's a cylinder
A cylinder has two bases that are both circles, as well as one lateral rectangle (surface) that is between the two circles and curved around their edge to form a cylinder.

The definition of lateral area is surface area without the bases
the formulas for lateral area dont include the figures bases. surface area does.
Lateral surface :)
A cylinder
The surface area of a (closed) cylinder equals the surface area of both bases (the top and bottom), i.e. pi x radius squared (first base) + pi x radius squared (second base), plus the lateral surface area (the surface area of the curved side), i.e. circumference (pi x diameter) x height. Inserting the numbers: SA = pi x (2 m.) squared + pi x (2 m.) squared + pi x 4 m. x 6 m. = pi x 4 m. squared + pi x 4 m. squared + pi x 24 m. squared = 8 x pi m. squared + 24 x pi m. squared = 32 x pi meters squared.

No, there are TWO bases.

It depends whether you want lateral or surface area. Lateral area is only the area of everything except the two bases. Surface area is the total area. Lateral area formula: pH or perimeter(of base) x height In this case, since this is a cylinder, the perimeter will be pi(diameter). Surface area: pH + 2B B= area of base So the equation would be: 10pi(9) + 2(pi x 5 squared)
