Answer:
Height of an oak tree= 9 meters
Height of a pine tree = 12 meters
Step-by-step explanation:
Given:
The combined height of 1 oak tree and 1 pine tree = 21 meters
Height of 4 oak trees = 24 meters more than 1 pine tree
To find the height of 1 pine tree and height of one oak tree.
Solution:
Let the height of one oak tree be = meters.
Let height of one pine tree = meters.
Combined height can be given as :
-------------[1]
Height of 4 oak trees = 24 meters more than 1 pine tree
The above statement can be given as :
------------[2]
Rearranging equation [2] by subtracting both sides by .
-------------[2]
Adding rearranged equation [2] to [1].
+--------------------
Dividing both sides by 5.
∴
Plugging in in equation [1]
Subtracting both sides by 9.
Height of an oak tree= 9 meters
Height of a pine tree = 12 meters
First we want to know the surface of the circle, which is
with r representing the radius. In this case
To find the volume of the cylinder we have to multiply this outcome with the height.
Hence, the volume of the cylinder is about 5024 cubic cm.
