How many​ flowers, spaced every 6​ inches, are needed to surround a circular garden with a 20

Question

​-foot
​radius?

Answer 1

To find the circumference of the circular garden, we use the formula:

C = 2πr

where r is the radius of the garden. Plugging in r = 20 feet, we get:

C = 2π(20) = 40π feet

Now we can divide the circumference of the garden by the spacing between the flowers to find the number of flowers needed:

40π feet / 6 inches = (40π * 12) flowers = 481 flowers

Therefore, 481 flowers spaced every 6 inches are needed to surround the circular garden with a 20-foot radius.
