An arithmetic sequence is a sequence with the difference between two consecutive terms constant. The difference is called the common difference. A geometric sequence is a sequence with the ratio between two consecutive terms constant. This ratio is called the common ratio.
10 pancakes produces 8 inches in diameter.
The area of 1 pancake is
Area = pi * r^2
Area = pi * 4^2
Area = 50.27 in^2
Then multiply it by 10
Total area = 502.65 in^2
A smaller pancake
Area = pi * r^2
Area = pi * 2^2
<span>Area = 12.56 in^2
Divide 502.65 by 12.56
= 502.65 / 12.65
= 39.74
So there are 39 pancakes.
