Question

Douglas is placing strings of lights around the edge of a circular patio with a diameter of 7.5 m. The lights are in lengths of 1.45 m. What is the best approximation for how many strings of lights Douglas needs? Use 3.14 to approximate for π .

Answer 1

17

I know the other answer is verified but is wrong.

Explanation:

Answer 2

Here, Circumference = Diameter * π
C = 3.14 * 7.5
C = 23.55

Now, Number of strings = 23.55 / 1.45 = 16.24

In short, He needs approx. 16 strings

Hope this helps!
