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.
Circumference = Pi x d: 3.14 x 24 = 75.36 feet
Circumference = 2 x pi x radius = 24 pi 2 x radius = 24 ; radius = 12 units
the answer is 75.36800285107463826459265926640261836577261120365428123494831029384756 also if you want the exact form (approximate form above) it is 24(pi symbol)
A = pi r2 = 2 x aprox 3.141593 x 122 = 904.8 square inches C = 2 x pi x r = 2 x aprox 3.141593 x 12 in = aprox 75.4 inches
