Answer:
576 sq cm
Step-by-step explanation:
For example imagine a rectangle, the area of which is width * height = area
If you multiply the dimensions by 2 you multiply the width AND the height which is 2 * width * 2 * height = 4 * width * height
This is true for all scalings, if you times the dimensions by n, you times the area by n^2
144 * 2^2 = 576
Given that the crust formed is cylindrical with the height which is equal to the radius of the sphere, then the volume will be given by:
V=πr^2h
V=π*8^2*12
V=2,412.743 cm^3
We conclude that the volume of the crust is 2,412.743 cm^3
