Answer:
B. m∠B = 80°
Step-by-step explanation:
Supplementary angles are two angles that sum to 180°
⇒ m∠A + m∠B = 180°
⇒ 100° + m∠B = 180°
⇒ m∠B = 180° - 100°
⇒ m∠B = 80°

hope this helps!!
The Formula to find the Area of a circle using the radius is:
r = 8
So:
And you get about 201.06193
So, the area of a circle with a radius of 8 is about 201.06
