Question

A landscaper is creating a circular flower bed with a diameter of 12 feet and wants to add a border of flexible landscape edging. The edging is sold in 4-foot lengths. What is the minimum number of whole edging lengths that need to be purchased to encircle the bed? (Ignore the thickness of the edging) (r = 3.14)

Answer 1

10

Explanation:

The diameter is 12 feet, so the circumference is 12π ≈ 12 × 3.14 = 37.68 feet.

The edging is sold in 4 foot lengths, so the number of pieces needed is:

37.68 ft / 4 ft = 9.42

Rounding up to the nearest whole number, the landscaper needs at least 10 pieces.
