Answer:
Step-by-step explanation:
If you want to factor this, you have to use the quadratic formula to do so.

For us, it looks like this:

which simplifies to

Since it breaks every mathematical rule to have a negative number under an even index radical, we have to deal with that using the imaginary "i". You should know at this point that 
so we will do a rewrite on that equation above:

which simplifies further to

This is the answer but we can separate it into its proper standard form which is
and

Answer:1250 units
Step-by-step explanation:
circumference=7850
Radius=?
Radius=circumference ➗ (2xπ)
Radius=7850 ➗ (2 x 3.14)
Radius=7850 ➗ (6.28)
Radius=1250 units
29 because the original answer would have been 28.26
