Orifice tubes are A. coded in American models only. B. coded by number for easy identification. C. similarly but not exactly siz

timurjin [86]

I'd go for (C) similarly but not exactly sized

Basically, to explain an orifice tube in Layman’s context, it is a car’s air conditioning system and is the exact place where the cold happens. Not all orifice tubes are standard sized and this means that different model vehicles use different sizes. These tubes are often color-coded for easy identification.

6. Consider a circle of diameter d cm.

blagie [28]

Circles

Area of Circle is $\pi d^{2} /4$

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) = $\pi r^{2}$

A = $\pi (d/2)^{2}$

A = $\pi d^{2} /4$

The area of circle is $\pi d^{2} /4$

(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%
