Question

WILL GIVE YOU THE BRAINLIEST !!!!!!!!!!!!!!!!!!!!!The radius of a circle is 15. Using π, which equation expresses the ratio of the circumference to the diameter of a circle?

Answer 1

Answer:

radius of circle = 15

circumference of circle  = 2πr

                                        = 2*22/7*15

                                        = 44/7*15

                                        = 660/7

                                       = 94.28

diameter of circle = 2r

                              = 2(15)

                              = 30

                                 

RATIO = 94.28:30
