Answer:
14.9 cm
Step-by-step explanation:
To find c using the Law of Sines, you must know angle C. That is found from ...
C = 180° -A -B = 180° -150° -12° = 18°
Then the law of sines tells you ...
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)
c ≈ 14.9 cm
The surface area of a sphere of radius r is A = 4π*r^3.
Since the radius in this case is 8 cm (half the 17 cm diameter), the area of this sphere is
A = 4π(8 cm)^2, or 256π cm^2.
