Question

The circumference of a circle can be found using the

formula C = 2rer.
Which is an equivalent equation solved for
r = CT
Or= C(20)
O
ra
2T
2m
re
쯘

Answer 1

C /2pi = r

Explanation:

The circumference of a circle is given by

C = 2 * pi*r

We want to solve for r

Divide each side by 2 pi

C / 2pi = 2*pi*r / 2pi

C /2pi = r
