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
Area = 12.56 in^2
Divide 502.65 by 12.56
= 502.65 / 12.65
= 39.74
So there are 39 pancakes.
