Question

How many​ flowers, spaced every 3 ​in., are needed to surround a circular garden with a 125 ​-ft ​radius? Use 3.14 for (the pie symbol).

Answer 1

785

Explanation:

flowers needed to surround the garden = circumference of the garden / space

circumference of a circle = 2nr

n = 3.14

r = radius

The radius is in ft and the space is in inches. i would convert the ft to inches to aid comparability

1ft = 12 inches

125 x 3 = 375

2 x 3.14 x 375 = 2355

flowers needed = 2355 / 3 = 785
