V = (1/3) pi r^2 h
103.67 = (1/3) pi r^2 11
r^2 = 103.67 / ( 1/3 * pi * 11) = 9
r^2 = 3 answer
Answer:
-5
Step-by-step explanation:
The answer is A. 76°.
The sum of the angles in a quadrilateral equals 360°.
Let the unknown angle be x.
The sum would be:
x+74°+93°+117°=360°
x+284°=360°
x=360°-284°
x=76°
