Answer:
C
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = 
area of base × height
= × πr² × height
Here diameter = 22, thus r = 11 and h = 22
V = × π × 11² × 22
= × π × 121 × 22
= 
≈ 2787.64 → C
We know that one regular hexagon is consist of the six equilateral triangles.
One of this is ΔAFM every angle in this triangle worth 60°, according to this
∡AFM=60°.
ΔABC is isosceles triangle with angle ∡ABC=120°, because every interior angle in regular hexagon worth 120°.
Angles ∡BAC=∡BCA=30°. Total sum of angles in one triangle is 180°.
∡ACF≅∡BCA=30° at the end we can conclud that angle ∡FAC=90° WHY?
Good luck!!!

Answer:
yes
Step-by-step explanation:
since 8 = 4*2, any number of the form 8x can be written as 4*2x. so every number divisible by 8 is also divisible by 4.
