Question

The circumference of a circle can be found using the

formula C = 2xr.
Which is an equivalent equation solved for I?

Answer 1

r=C/(2\pi)

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)
