What is the Surface Area of this pyramid?
A)96
B)101
C)106
D)111

A

Step-by-step explanation:

(2 * sqrt(5^2 - 4^2))^2 = 36

4 * 1/2 * 5 * 6 = 60

60 + 36 = 96

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.
