Surface Area of Cylinders

Radius = 10ft
Height = 6ft

The area of most three-dimensional geometric shapes is

A = a · h

Area = area of the base · height of the figure.

In this case, the area of the base is the area of a circle, so a = πr²:

a = 10²π

a = 100π ≅ 314

Now, all we have to do is multiply the area of the base to the height:

A = 100π · 6

A = 600π                            ← In terms of "π"

A ≅ 1884                             ← Rounded answer

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
