How many flowers spaced every 3inches are needed to surround a circular garden with a 125ft radius? Use 3.14 for pi
Circumference = 2 · pi · radius.
Since the garden has a 125 foot radius, the circumference is 2 · pi · 125'
But, we need the answer in inches, so multiply that answer by 12.
To find out how many flowers are needed, divide the last answer by 3".
