Question

Landscape is designing a display of flowers for an area in a public park. The flower seeds will be planted at points lie on a circle that has a diameter of 8 feet. The point where seed is planted must be at least 2 feet away from seeds on the either side of it.
b. After planting the flower seeds, the landscaper has 20 seed left over. The landscaper wants to plant all, the remaining seeds in another circle so that the seeds are 2 feet apart. What is the diameter of the smallest circle that the landscaper Canute to plant all of the remaining seeds.
I am struck in this for an hour but I did not get. I need help.

Answer 1

the circumference is 8π ft. 2 ft per flower means you get 8π/2 = 4π ≈ 12 plants

20 seeds @ 2 ft/seed means a circle with a 40 ft circumference. So, the diameter is 40/π ≈ 12.75 ft

Answer 2

thank you
