The formula for radius is 
.
First we need to see what 8*π is, put it in your calculator and you will get . So now we know the exact circumference, so now put that into the equation to find the radius.
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY!

v = 4π r²h is to be solved for r.
Divide both sides of this equation by 4π*h:
v
--------- = r^2
4π*h
Next, take the positive square root of both sides:
v
r = √[----------- ]
4π*h
You may leave this result as is, or proceed further: Taking the + square root of 4 results in:
v
r = (1/2)√[----------- ]
π*h
F(x) = √(5x + 7)
g(x) = √(5x - 7)
(f + g)(x) = f(x) + g(x)
(f + g)(x) = √(5x + 7) + √(5x - 7)
