To find the circumference of the circle, we use the formula:
Circumference = 2πr
Where r is the radius of the circle and π is approximately 3.14.
Substituting r = 50 feet, we get:
Circumference = 2π(50) = 100π ≈ 314.16 feet
Since the flowers are spaced 6 inches apart, we need to convert feet to inches:
314.16 feet × 12 inches/foot = 3769.92 inches
To determine how many flowers are needed, we divide the circumference by the spacing between the flowers:
3769.92 inches ÷ 6 inches/flower ≈ 628.32 flowers
Since we can't have a fraction of a flower, we round up to the nearest whole number:
628.32 ≈ 629 flowers
Therefore, we need 629 flowers to surround the circular garden with a 50-foot radius, spaced every 6 inches.
How many flowers, spaced every 6 inches, are needed to surround a circular garden with a 50
-foot
radius?
