1. Find the length of AB. Round it to the nearest hundredth.

Given that the radius of the circle is 6 cm.

The central angle is 120°

We need to determine the length of AB.

Length of AB:

The length of AB can be determined using the formula,

Substituting and in the above formula, we get;

Simplifying the values, we get;

Substituting π = 3.14, we have;

Thus, the arc length of AB is 12.56 cm

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

answer:

24pi or letter c
