Answer:
The circumference of the circle = 26π unit.
Step-by-step explanation:
Given:
Radius of the circle, r = "x+6"
Diameter of the circle, d = "3(x)+5"
We have to find the circumference of the circle in terms of pi.
Formula to be used:
Circumference of a circle = 2πr or πd
As we know that:
Radius = Half of diameter
So,
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
...<em>Arranging variables and constants. </em>
⇒ 
Plugging x = 7 we will find the radius and the diameter.
⇒ Radius = "x+6" = "7+6" = 13
⇒ Diameter = "3(x)+5" = 3(7)+5 =26
Lets find the circumference of the circle.
⇒ Circumference = 
Or
⇒ Circumference = 
The circumference of the circle = 26π unit.
The process of expressing w in terms of A and l is called transposition or changing the subject of the formula. The methods used to change the subject of the formula are the same as those used for solving equations.
5 no mater what on first hour so, then on the second hour the 1.75 rate kicks in so therefor when x=1, then y=5 so y=5+0 times 1.75
so y=5+1.75 times (x-1)
the naswe ris
y=1.75(x-1)+5 or d
