Which of the following segments is a radius of k? a) rt b) mt c) km d) mr

Observe the given figure, we have to determine the segments which is a radius of K.

1. RT is a diameter of a circle K as it is a straight line passing from side to side through the center of a circle.

2. MT is a chord of a circle K as it is the line segment connecting two points on a circle's circumference.

3. KM is a segment which is a radius of circle K as it is the length of the line from the center to any point on its edge.

4. MR is a chord of a circle K as it is the line segment connecting two points on a circle's circumference.

So, KM segment is a radius of circle K.

Therefore, option 3 is the correct answer.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
