Circumference = 2πr
3π=2πr
r=3π÷2π
r=3/2
area of a circle= πr²
=π×(3/2)²
=2.25π
Answer:
x<=-2
Step-by-step explanation:

If B is the center of that circle, then that statement is definitely false. A central angle's degree measure is equal to the measure of the arc which it intercepts. Keep in mind that arcs can be measured according to their LENGTH or to their DEGREE, and they are both very different from one another. If arc AC is 65°, then the measure of angle ABC is also 65°
