I believe the correct answer is C.
The volume of any solid whose base is uniform is V = Ah. Since
the base is a sector of a circle, it’s area is defined by the equation A = θ (r^2)/2, where θ is in radians.
90 degrees in radians
is Pi/2. So the A = (PI) (r^2)/4
Therefore, V = [(PI) (r^2)/4]*h
Its c cause its like method or principle of reasoning
Answer:
3.1
Step-by-step explanation:
3 1/2=3.5
2/5=0.4
3.5-0.4=3.1
