Answer:
Half; twice
Step-by-step explanation:
In a circle, the radius is said to be the distance from the center of the circle to any point on the edge of the circle, it is denoted as "r". The radius is called a radii if it is more than one.. The radius of a circle is half the length of the diameter of a circle because the diameter of a circle is the distance of the line that passes through the center of a circle touching both edges of the circle. It is denoted as "d".
Thus,
2r = d
r = d/2
For example, if the radius of a circle is 10cm, the diameter of the circle will be calculated as: d = 2 * 10 = 20cm. Which means if the radius is 10cm, diameter will be 20cm.
Therefore, the radius of a circle is half the length of its diameter. the diameter of a circle is twice the length of its radius

Answer: C. I, II, and III only</h3>
Basically everything but statement IV is true
Horizontal lines always have a slope of 0 to indicate no rise is going on.
Vertical lines have undefined slopes which you can see through the slope formula (recall that you cannot divide by zero).
Line 'a' goes through the point (5,0) making statement III true. However, statement IV is false because (-5,0) is not on line b. Line b is parallel to the x axis, so it does not have an x intercept.
