210 (idk maybe since I think this is multiplication)
So, I need more details, is 3.14 the radius or is 100 the radius. Or is it the diameter???
Answer: D
Step-by-step explanation: payment equals to money earned per hour (p=6.25h).
A = (45/360)×16^2×pi
A = 32pi

Answer: 54 degrees (third choice)</h3>
Explanation:
AB is a diameter of circle C. This leads to angle ACB being 180 degrees. By Thales Theorem (a special case of the inscribed angle theorem) we know that angle D is 90 degrees.
Therefore, triangle ADB is a right triangle. The acute angles (A and B) add to 90, and we can say they are complementary angles.
A+B = 90
36+B = 90
B = 90-36
B = 54 degrees
