Calculator Reference A covered water tank is in the shape of a cylinder. The tank has a 28-inch diameter and a height of 66 inches. To the nearest square inch, what is the surface area of the water tank?

Step-by-step explanation:

We have been given that a covered water tank is in the shape of a cylinder. The tank has a 28-inch diameter and a height of 66 inches. We are asked to find the surface area of the water tank.

We will use surface area of cylinder to solve our given problem.

, where,

SA = Surface area of cylinder,

r = Radius of cylinder,

h = Height of cylinder.

Radius of the given cylinder would be half the diameter that is inches.

Upon rounding to nearest square inch, we will get:

Therefore, the surface area of the water tank is approximately 7037 square inches.

step-by-step explanation:

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.
