Answer:
Step-by-step explanation:
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!!!
Definitely A, its direct fast and straight to the point the other ones seem extremely extra<span />
Answer:
1520.5 cm²
Step-by-step explanation:
Surface area of a sphere =
A = 4πr²
= 4 x π x (11)²
= 1520.530844
= 1520.5 cm²
