Answer:
circle of radius 27 inches
Step-by-step explanation:
Anywhere a plane cuts a sphere, the cross section is a circle. When the plane includes the center of the sphere, the circle has the same radius the sphere has.
The cross section is a circle of radius 27 inches.
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.
