Answer:
[See Below]
Step-by-step explanation:
✦ First split the equation in little pieces and solve them:
✧ 4 - 16 = -12
✧ 4 + 4² = 20 (4² = 16)
✦ Now divide them:
✧ -12 ÷ 20 = -0.6
So I'm guessing you're trying to simplify 4²... so it'd be 16 because none of the choices are the simplified version of the problem.

Answer:
The circumference of a circle is the distance around the entire circle, while arc length, s, is the distance <u>between</u> two points on the circle.
C = 2πr = 2π( <u>5</u><u> </u>) = 10π ≈ 31.4 units
3.14 is an approximation for π.
s = θ/360° (C)
mAB = 60°/360° ( 31.4)
= <u>1</u><u>/</u><u>6</u>(31.4) ≈5.2 units
The area is 7.07
