Cylinder A has a volume of 360 cm3. Cylinder B has a base and height identical to that of the cylinder B, but it is the right in
such a way that its slant length is greater by 4 cm. What is the volume of cylinder B?
2 answers:
<u>Answer:</u>
360 cm
<u>Step-by-step explanation:</u>
Here, one cylinder is right and the other cylinder is oblique or slanted.
In geometrical context, an object which is distorted so that it seems to lean over at a certain angle, in comparison to being completely upright is called an oblique object. While the right objects are exactly upright.
Since both the cylinders have the same base and height, so their volume is not affected by the lean of the cylinder B.
Therefore, cylinder B has the same volume as cylinder A i.e. 360 cm.

Answer:
(a)
- The vertices are at (0,-5) and (0,5).
- The coordinates of the foci are (0,-3) and (0,3).
- Eccentricity=3/5
(b)Length of the major axis=10
Step-by-step explanation:
When the major axis of an ellipse is parallel to the y-axis.The standard form of the equation of an ellipse is given as:
Given the equation:
(I)The coordinates of the vertices are
Therefore, the vertices are at (0,-5) and (0,5).
(II)The coordinates of the foci are
The coordinates of the foci are (0,-3) and (0,3).
(III)Eccentricity
This is the ratio of the distance c between the center of the ellipse and each focus to the length of the semi major axis.
Simply put, Eccentricity =c/a
Eccentricity=3/5
(b)Length of the major axis
The length of the major axis=2a
=2(5)=10.
