Enrique is given information about a satellite orbiting earth. r = 3.8 × 108 m t = 18 days in order to calculate the tangential speed of the satellite, what should enrique do first?

Tangential speed, just as any other speed, is calculated by dividing the distance traveled by the time or duration. From the given above, the very first thing that needs to be done is to calculate for the circumference through the equation,
                                            C = 2πr
Substituting,
                                            C = 2π(3.8 x 10⁸) = 2.388 x 10⁹ m
Then, divide this value by the time, 18 days,
                                              rate = 1.326 x 10⁷ m/days

Iam looking for this answer too!
