Answer:
D) A rendering engine displays content on the screen and a browser engine coordinates user interface interactions.
Explanation:
The rendering engine will deal with all the HTML code and will generate an output based on its own rules for interpreting the code. That's why different rendering engines will have different renditions of the same given HTML code. You can notice that in the acceptance of HTML5 and CSS3 tags, which are not universal yet.
The browser engine will deal with the user interface and all other features that make a browser a browser, relying on the rendering engine for the display.
That duality allows different browsers to use the same rendering engine, thus have similar outputs.

Circles
Area of Circle is 
Total percentage increase in the area of the modified circle is 69%
Explanation:
(a) Given the diameter of the circle be d
Then the radius of the circle = r = d/2
and the area of the circle is given by:
Area(A) =
A = 
A = 
The area of circle is 
(b)
The increase in percentage while changing the dimensions is given by the formula :
Total % increase = a% + b% - (a% * b%)/100
Where ,
a% is the percentage increase in side a
b% is the percentage increase in side b
Let the percentage increase in radius is : a%
Since a% = b%
So the formula is
Total increase % = a% + a% + (a% * a%)/100
Given here the diameter of the circle increases by 30% so a =30
Therefore, putting the value of a in the formula
Total increase % = 30% + 30% + (30% *30%)/100
Total increase % = 60% + 9%
Total increase % =69%
Therefore the total percentage increase in the area of the modified circle is 69%
