Question

The ratio of the the two radii of two hula hoops is 3:4 what is the ratio of their circumferences

Answer 1

Answer:

Step-by-step explanation:

here, radius of 1st hula loop is given 3 and the 2nd is 4

hence the diameter of the loop 1 become 6 and the loop 2 become 8

circumference of the hula loop = $\pi$*d

circumference of loop 1st =3.14*6                                                    

                                           =18.84 units

circumference of loop 2nd =3.14*8

                                            =25.12 units

hence, the ratio of their circumferences = 18.84/25.12

                                                                    =0.75
