Brown = 2x because of the equation done
Answer:
D. 151 cu. in.
Step-by-step explanation:
Given: Cone; Radius = 4 in, Height = 9 in.
To find: The volume of the specified cone
Formula: 
Solution: A cone is a solid that has a circular base and a single vertex. To calculate its volume multiply the base area (area of a circle: π × r²) by height and by 
: volume = ( ) × π × r² × h.

AE and EC are congruent because it's given that E is the midpoint of AC. However, DE and EB cannot be congruent because it does not state that point E is the midpoint of DB.
You cannot assume that all the triangles DEA, AEB, BEC, and CED are all congruent just from being given that E is the midpoint of AC. You would need to be given other information such as "Quadrilateral ABCD is a parallelogram. "
