A full circle in radians is 2π, and in degrees it's 360°. I want to convert the 72° to radians:

72° in radians = 72/360 * 2π = 2/5π

The circumference of a full circle is the number of radians times the radius. (ie., 2πr), so the JK part of the circle is:

5* 2/5π simplifies to 2π

Answer:

-44

Step-by-step explanation:

If the input is -28, that means x = -28, so we plug -28 in for x and solve for y, which is the output:

y = -28 - 16 = -44

The answer is thus -44.
