Question

Douglas is placing strings of lights around the edge of a circular patio with a diameter of 7.5 meters. The lights are in lengths of 1.45 meters. What is the best approximation for how many strings of lights Douglas needs? HURRY I WILL BRAINLIEST!!!!!!!

Answer 1

So first you need the find the circumference 
which is the diameter multiply pi (simplified to 3.14)
7.5*3.14=23.55
so divide 23.55 and 1.45
which is this painfully long number
16.2413793103
but you should round UP because its fine to have more than not enough
so about 17

Answer 2

17 is the correct answer hope this helps, and have a nice day
