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.

21x + 28 = 156 - 2
21x = 154 - 28
21x/21 = 126/21
X = 6
In fix fraction it will be, 1 7/8
and the exact answer is 15/8
and in decimal from it will be, 1.875
