Answer:
126
Step-by-step explanation:
A line is 180 degrees. I found the degree of the angles in-between 126 and M by subtracting 126 from 180. This means that M is also 126. (Plus the intersecting lines are parallel)
A=pi radius^2
7 is the radius
Pi7^2=153.93
127.23cm should be the surface area!
3=36/12
11/12x36/12
396/144
2 3/4
