ANSWER
The radius is approximately 1249 units.
EXPLANATION
The relation between the radius of a circle and its circumference is expressed in the formula:
[tex]C = 2\pi \: r[/tex]
The circumference is given as 7,850 .
This implies that
[tex]7850 = 2\pi \: r[/tex]
[tex]r = \frac{7850}{2 \: \pi} [/tex]
[tex]r = 1249.4[/tex]
to the nearest tenth.
