The expression of the ellipse is:
Step-by-step explanation:
The equation of a ellipse can be written by the following expression:
Where 2a is the length of the major axis and 2b is the length of the minor axi. Since we were given the length of the minor vertex, then:
The length of the major axis is the distance between the two vertices.
Therefore the expression of the ellipse is:
Actually Welcome to the concept of Surface Areas and Volume.
==> Volume of Cylinder = πr^2h
==> 27π = πr^2(3)
==> 27 = r^2 (3)
==> r^2 = 9
==> r = 3 inch
hence the radius is 3 inches.
