TheThe area of the shaded region if the radius of the outer circle is 4 and the radius of the inner circle is 2 is 12π.
<h3>Area of the shaded region</h3>Area of a circle = πr²
r =radius of the circle
Area of the outer circle:
Area of the outer circle = π(4)²
Area of the outer circle = 16π
Area of the inner circle:
Area of the inner circle = π (2)²
Area of the inner circle = 4 π
Area of the shaded Region :
Area of the shaded Region = 16π - 4 π
Area of the shaded Region = 12π
Therefore the area of the shaded region if the radius of the outer circle is 4 and the radius of the inner circle is 2 is 12π.

Answer:
A) F(x) = 50 + ( x - 10 )*9
B) Graph
C) lim ( x ⇒ 10) F(x) = 50
Step-by-step explanation:
A) F(x) = 50 + ( x - 10 )*9 since the first 10 hours are included in initial fee
B) In Annex
C) lim (x ⇒ 10) F(x) = 50 + ( 10 -10)*9
lim ( x ⇒ 10) F(x) = 50 + 0
lim ( x ⇒ 10) F(x) = 50
The perimeter of the equatorial triangle is 24 units
<h3><u>Solution:</u></h3>Given that,
An equilateral triangle has an height equal to
The triangle is shown below
From Triangle ABC in the shown figure AD
Let the sides of the equilateral triangle be ‘a’
AB = BC = a
Since, it is an equilateral triangle we get,
BD = DC = a ÷ 2
Now, using Pythagoras Theorem in Triangle ABD,
The Pythagorean theorem is this: In a right triangle, the sum of the squares of the lengths of the two legs is equal to the square of the length of the hypotenuse.
a = 8
Hence, the three sides of the triangle are 8 units each
In equilateral traingle, length of all three sides of triangle are equal
So, Perimeter = 3 (Length of each side of triangle)
Perimeter = 3 8 = 24
Thus the perimeter of the equatorial triangle is 24 units
