Question

The circumference of a circle can be found using the formula C = 2r.

Answer 1

Answer:

$r=C/(2\pi)$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

where r is the radius of the circle

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

so

Divide by $2\pi$ both sides

$C/(2\pi)=2\pi r/(2\pi)$

$r=C/(2\pi)$

Answer 2

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