Answer:
Step-by-step explanation:
Circumference of the column
Circumference of a circle
Therefore:
Area of a Circle
Since radius of the cross section of the column =9 meters
Area of the cross section of the column
Answer:
c
Step-by-step explanation:
you have to turn the48 to a decimal
Given:
ratio of altitude height = 2/3
Required:
ratio of volume
Solution:
Assuming that the only difference that the cylinders has is the height, we can solve for the ratio of the volume.
The volume of a cylinder is equal to πr²×height.
ratio of volume = πr²×2/πr²×3
We cancel the pi and the r² since we assume that the cylinders have the same radius.By cancelling, we are left with:
ratio of volume = 2/3
