Question

How many flowers, spaced every 4 inches, are needed to surround a circular garden with a 200 inch radius?

Answer 1

Find the distance around the circle ( circumference)

Circumference = 2 x PI x r

Circumference = 2 x 3.14 x 200

Circumference = 1256 inches.

Divide circumference by spacing:

1256 / 4 = 314

You can plant 314 flowers.
