Answer:
Step-by-step explanation:
First find the slope,
m=(y2-y1)/(x2-x1)=(1-(-9))/(7-6)=10
Next, use the point slope form to find the equation:
L : y-y1=m(x-x1) => y-1=10(x-7)
[in point slope form, point is (7,1), slope=m=10 ]
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
Rational, because they follow a pattern and end. They make sense.
