Question: How many decorative bricks 10 inches long would be needed to go around a circular garden that is 8 feet in diameter? Use Pi = 3.14
According to the book the answer is "about 30".
This is what I did
Step 1: I read the problem and decided that it is asking me to find the perimiter. I used the formula pi x d. The answer I got was 25.12. How did the author get 30? Am I doing something wrong? I have spent over an hour trying to figure it out.
