Hello. You forgot to put the image that complements this question.
The image is attached below:
Answer:
A = 38.465.
Explanation:
To arrive at the result you will have to perform a very simple calculation, using the fromula shown in the question above.
First, it will be necessary to find the diameter of the figure, to
therefore, you will have to divide, which will result in 3.5.
You can now replace the values in the formula: A = (3.14) (3.5) ² = (3.14) (12.25)= 38.465.
This happens because when leaf are submerged it is using light to continue process of photosynthesis, this process includes the release of oxygen that we see in bubble format .
<h3>Why the gases came out of the leaf when it was put into warm water?</h3>
When the leaf is put in warm water it is using light to continue the process of photosynthesis. Part of this process is to let oxygen out of the leaves. It is this oxygen that you are seeing as bubbles in the water.
<h3>Which part of the leaf the gas came from?</h3>
The only way for gases to diffuse in and out of the leaf is though small openings on the underside of the leaf, the stomata.
