(a)
To find:The ratio of the heights of two cylinders.
(a)
Answer to Problem 3WE
The ratio of the heights of two cylinders is
Explanation of Solution
Given information:Two similar cylinders have radii
Calculation:
As given both the cylinders are similar. So, the scale factor is equal to the ratio of the radii of the two cylinders.
The ratio of the radii of two cylinders is
Therefore, the ratio of the heights of two cylinders is
(b)
To find:The ratio of the base circumferences of two cylinders.
(b)
Answer to Problem 3WE
The ratio of the base circumferences of two cylinders is
Explanation of Solution
Given information:
Two similar cylinders have radii
Calculation:
As given both the cylinders are similar. So, the scale factor is equal to the ratio of the radii of the two cylinders.
The ratio of the radii of two cylinders is
Therefore, the ratio of the base circumferences of two cylinders is
(c)
To find:The ratio of the lateral areas of two cylinders.
(c)
Answer to Problem 3WE
The ratio of the lateral areas of two cylinders is
Explanation of Solution
Given information:Two similar cylinders have radii
Calculation:
As given both the cylinders are similar. So, the scale factor is equal to the ratio of the radii of the two cylinders.
The ratio of the radii of two cylinders is
So, the ratio of lateral areas of two cylinders is:
Therefore, the ratio of the lateral areas of two cylinders is
(d)
To find:The ratio of the volumes of two cylinders.
(d)
Answer to Problem 3WE
The ratio of the volumes of two cylinders is equal to
Explanation of Solution
Given information:Two similar cylinders have radii
Calculation:
As given both the cylinders are similar. So, the scale factor is equal to the ratio of the radii of the two cylinders.
The ratio of the radii of two cylinders is equal to
Therefore, the ratio of the volumes of two cylinders is equal to
