Answer:
The area of the new circle is 
Step-by-step explanation:
Given:
radius of the circle = 3 in.
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared.
Let
z-----> the scale factor
x-----> the area of the enlarged circle
y-----> the area of the original circle
So;

In this problem we have
----> the scale factor
The area of the original circle is equal to

Now substituting value of y and solve for x we get;

Hence Area of the new Circle is 
Also The area of the enlarged circle is 16 times the area of the original circle.

Answer:
c₁ = 1/2 cos⁻¹ (2/π) = 0.44
c₂ = -1/2 cos⁻¹ (2/π) = -0.44
Step-by-step explanation:
the average value of f(x)=2 cos(2x) on ( − π/ 4 , π/ 4 ) is
av f(x) =∫[2*cos(2x)] dx /(∫dx) between limits of integration − π/ 4 and π/ 4
thus
av f(x) =∫[cos(2x)] dx /(∫dx) = [sin(2 * π/ 4 ) - sin(2 *(- π/ 4 )] /[ π/ 4 - (-π/ 4)]
= 2*sin (π/2) /(π/2) = 4/π
then the average value of f(x) is 4/π . Thus the values of c such that f(c)= av f(x) are
4/π = 2 cos(2c)
2/π = cos(2c)
c = 1/2 cos⁻¹ (2/π) = 0.44
c= 0.44
since the cosine function is symmetrical with respect to the y axis then also c= -0.44 satisfy the equation
thus
c₁ = 1/2 cos⁻¹ (2/π) = 0.44
c₂ = -1/2 cos⁻¹ (2/π) = -0.44
