Answer:

A=351.68\ cm^2

Step-by-step explanation:

we know that

The area of the shaded region is equal to subtract the area of the smaller circle from the area of the larger circle

so

A=\pi(r_b^2-r_a^2)

we have

r_b=11\ cm ----> radius of large circle

r_a=3\ cm ----> radius of smaller circle

assume

\pi=3.14

substitute

A=3.14(11^2-3^2)=351.68\ cm^2

F(x) = x ^ 2 . What is g(x) ?
Bond [772]

Given:

The function is:

f(x)=x^2

The graphs of functions f(x) and g(x).

To find:

The function g(x).

Solution:

We have,

f(x)=x^2

The function f(x) is vertically compresses to get the graph of the function g(x). So, the function g(x) is:

g(x)=kf(x)

g(x)=kx^2               ...(i)

From the given graph it is clear that the graph of the function g(x) passes through the point (3,3). So, putting x=3 and g(x)=3 in the above function, we get

3=k(3)^2

3=9k

\dfrac{3}{9}=k

\dfrac{1}{3}=k

Putting k=\dfrac{1}{3} in (i), we get

g(x)=\dfrac{1}{3}x^2

Therefore, the correct option is D.
