Radius is half of the diameter.
So because the area of a circle is A= pi • r^2, to find the radius first, we have to change the equation to solve for r. Now it is, r= square root of A/pi. We plug in 1134.1. (Look at pic)
The diameter is 38

x < -5 or x > 5
Step-by-step explanation:
x < -5 or x > 5
or can be written {x : x < -5 U x > 5} depending on which notation you use
Greatest place is the hundreds place so 800 - 200 = 600
Or 760 - 240 = 520 you can round the 520 to 500
Upper and lower bounds accordingly
So 600 and 500.
