Answer:The radius is one half of the diameter in measurement. The radius measures the distance from the very center of the circle to any point on the circle. You can calculate either of the measurements if you have the circumference of a circle.

Answer:
The answer is G, 24 1/2
Step-by-step explanation:
Hope this helps! :)
If the length of JK is 16.4 miles, it will be diameter of this circle, the radius will be JK/2 = 8.2 miles
As we know the length of circle is 2π*r in this case r = 8.2
The arc JM is 1/4 length of the whole circle so arc JM = (2π*8.2)*(1/4) = 2π*8.2/4 = π*8.2/2 = π*4.1
if we assume that π=3.14 the answer will be 3.14 * 4.1 = 12.874.... And as the answer needs to be rounded to the nearest tenth it will be 12.874≈12.9
So the answer will be 12.9
I agree. All real numbers except -1.
