In circle O, the radius is 4, and the
measure of minor arc AB is 120
degrees. Find the length of minor
arc AB to the nearest integer.

The length of minor arc AB is 8

Step-by-step explanation:

In this question, we are asked to calculate the length of the minor arc.

Mathematically, the length of an arc can be calculated using the formula below;

Length of an arc = θ/360° × 2πr

Where θ is the angle subtended by the arc which is 120° according to the question, r is the radius of the circle which is 4 according to the question.

Plugging these values, we have

Length of minor arc AB = 120/360 × 2 × 22/7 × 4 = 8.34 = 8 to the nearest integer

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
