  1. I started you with Part A in your last post. Now -- draw a picture to figure out how many seeds are needed around that circle.

    After you've found the answer to Part A, please post it, and I'll help you from there.

  2. I posted again because I did not understand how to calculate.

  3. (A): the circle has a circumference of 8π feet. If the seeds are at least 2 ft apart, then at most 8π/2 = 4π ≈ 12 seeds may be planted.

  6. How many seeds did the gardner have left over from Part A?

    Part B. Find the circumference. Divide by 20.

    C = pi * d

  7. 4pi/20

    is that right?
