When you know the diameter: divide the diameter by 2

When you know the circumference: divide the circumference by 3.14(pi) and then divide by 2

When you know the area: divide the area by 3.14(pi) and then find the square root of that.

Hope this helps!

Answer:

x= - $\frac{1}{32}$

Step-by-step explanation:

First move the x on the right side the the left side. Now your equation is

2x+ $\frac{1}{2}$ = $\frac{3}{8}$ Next move 1/2 to the right side. Now your equation is 4x= $\frac{-1}{8}$ . Next divide both sides by 4 to isolate "x." Now your equation is x= - $\frac{1}{32}$

Hope this helped and have a great day.
