Final answer:
To surround a circular garden with a 30-foot radius, approximately 377 flowers spaced every 6 inches are needed.
Step-by-step explanation:
To find out how many flowers are needed to surround a circular garden with a 30-foot radius, we need to calculate the circumference of the garden. The formula for circumference is C = 2πr, where π is approximately 3.14 and r is the radius. Plugging in the values, we get C = 2 * 3.14 * 30 = 188.4 feet. Since the flowers are spaced every 6 inches, we convert 6 inches to feet by dividing it by 12, which gives us 0.5 feet. Now, we divide the circumference of the garden by the spacing of the flowers: 188.4 / 0.5 = 376.8. Rounding to the nearest whole number, we need approximately 377 flowers to surround the circular garden.
