    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
