To find the circumference we must work backwards from the area to find the radius of the circle.
Area = pi x radius squared
4 x pi = pi x radius squared
4 = radius squared
2 = radius
Now that we have the radius, we can plug it into our formula for circumference.
Circumference = pi x diameter (or 2 x radius)
Circumference = pi x 4
Circumference = 4
Answer:
Rephrasing text material in your own words is an effective way to promote <u><em>deep processing.</em></u>
Explanation:
Deep processing can be described as a method of processing by the analysis of the language being used. Deep processing can easily be described as a way in which a word can be more easily remembered by associating with anything else that a person can remember. For example, using images or other easier words to remember a difficult word.
Rephrasing a text material is an effective deep processing method to remember a text.
Colonies of cyanobacteria benefit aquatic organisms because they can be an important source of food to organisms.
The problem with cyanobacteria is that they can be harmful and in an alga bloom then can cover the surface cutting off any light to other plants and producing toxins that kill fish and other life forms.
The organisms in an ecosystem that will likely be affected by a flood would be A. producers, consumers and decomposers.
