Answer:

1885 flowers

Step-by-step explanation:

Given that:

Radius, r of circle = 100 feets

The Circumference of the circke is thus ; 2πr

C = 2 * π * 100

C = 628.31853 feets

Converting feets to inches

1 foot = 12 inches

628.31853 feets = 628.31853 * 12 = 7539.8223 inches

If flowers are spaced at 4 inches :

Number of flowers that can be planted :

Circumference of circle / spacing

7539.8223 / 4

= 1884.9555 flowers

= 1885 flowers
