What is the shaded area?

44.24 cm^2

Step-by-step explanation:

The area of the circle is

A = pi r^2 = 3.14 *4^2 = 50.24

The area of the rectangle is

A =l*w = 2*3 = 6

Subtract the rectangle from the circle

50.24 - 6

44.24

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.
