This looks like gibberish to me. You'll probably need to clarify that before a math tutor can help you.
Stepping through or around all that gibberish, I read it as:
circumference = 50.24 units
radius = x+3
2πr = circumference
2π(x+3) = 50.24
x+3 = 50.24/(2π) =
x = 50.24/(2π) - 3
= ........
evaluate using your favourite method of doing arithmetic.
(I have a calculator that contains the constant π, giving me a slightly better answer than using 3.14 for π)
