Respuesta :

R=C/2(eliminate "2" from r by dividing both sides by 2)

Answer:

[tex]r=C/(2\pi)[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

where r is the radius of the circle

Solve for r------> means isolate the variable r

so

Divide by [tex]2\pi[/tex] both sides

[tex]C/(2\pi)=2\pi r/(2\pi)[/tex]

[tex]r=C/(2\pi)[/tex]
