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%
Answer:
A. Loopback tool
Explanation:
Loopback tool or adapter is a small device used to test networks ports and help identify simple network connection issues, this is a great tool when mapping out a physical layout of a network and quickly identify active ports on a switch.
This tool works by taking the transmitted signal and redirecting it or looping it back into the receiving end of the same connection.
Answer:
It is used in jewelry, tennis rackets, scissors, bicycle frames, surgical tools, mobile phones and some other high-performance products.

Explanation:
Pre-production formally begins once a project has been greenlit. At this stage, finalizing preparations for production go into effect. Financing will generally be confirmed and many of the key elements such as principal cast members, director and cinematographer are set. By the end of pre-production, the screenplay is usually finalized and satisfactory to all the financiers and other stakeholders.
During pre-production, the script is broken down into individual scenes with storyboards and all the locations, props, cast members, costumes, special effects and visual effects are identified. An extremely detailed shooting schedule is produced and arrangements are made for the necessary elements to be available to the film-makers at the appropriate times. Sets are constructed, the crew is hired, financial arrangements are put in place and a start date for the beginning of principal photography is set. At some point in pre-production, there will be a read-through of the script which is usually attended by all cast members with speaking parts, the director, all heads of departments, financiers, producers, and publicists.
