Question

In designing a circular flower bed where the diameter of the circle is 13 feet​ long, a gardener decides it would look best to space the flowers 7 inches apart. How many flowers will be needed around the outside of the flower​ bed?

(I've tried finding the circumference and dividing it by 7.. No idea how to do this. Some sort of formula?)

Thanks! (:

Answer 1

you have the right idea. but you need to change feet to inches, so the units match:

13π*12/7 = 70.01

So, there will be 70 spaces between flowers. Since they are in a circle, there will be 70 flowers.

Had they been in a line, there would have been 71, since the ends would each have a flower.

Thank you so much, Steve!!
