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 !

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

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

Ithink it would be 1.24 pounds
