For this case we have that the point-slope equation of a line is given by:

Where:
m: It is the slope of the line
It is a point through which the line passes
In this case we have to:

Substituting in the equation we have:

Answer:

We just need to replace the value of the slope
Answer:





Step-by-step explanation: the other angle is equal to his simmetrical, cause the triangle is isosceles, so is value is x. The sum of the angle in a triangle must be 180°
Answer: 5.43
Step-by-step explanation:
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
