How many flowers, spaced every 3 in., are needed to surround a circular garden with a 100 -ft radius? Use 3.14 for pi.

2512 flowers

Step-by-step explanation:

We need to find the circumference first

C = 2 * pi * r

C = 2 * 3.14 * 100

C = 628 ft

We need to convert this to inches

628ft * 12inches/ft = 7536 inches

We want the flowers every 3 inches, so we divide by 3

7536/3 = 2512

We need 2512 flowers
