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,

where is the central angle and r is the radius of the circle.

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

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
