A radius is a segment that connects any pount on the circle to the center of that circle

This is true.

Step-by-step explanation:

No matter where you put the dot on the circumference, the radius will connect to the center, and be the same distance.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
