Concentric means these circles would have the same center, thus, the smaller circle must be inside the bigger circle. Any tangent line to the smaller circle wont be a tangent line to the bigger circle, since that tangent line would intersect at the bigger circle at 2 points. Any tangent line to the big circle will not touch the small circle... so the answer would be 0.
Answer:11,256
Step-by-step explanation:
This is a 30-60-90 special triangle. in a 30-60-90 right triangle, the shortest leg is half of the hypotenuse, and the other leg is (√3)/2 of the hypotenuse,
so FA=(1/2)AD=7, DF=(√3)/2)*14=7√3
the area is (1/2)*7*7√3≈42.4
