A = area of the circle

A = pi*r^2

A = pi*11^2

A = 121pi

-----

B = area of the rectangle

B = length*width

B = 6*4

B = 24

-----

C = blue shaded area

C = A - B

C = 121pi - 24 which is the exact area in terms of pi

C = 356.1327 is what you'd get if you used a calculator

C = 356.13 is the result after rounding to the nearest hundredth

<h3>The final answer is 356.13</h3>

The domain for f(x) and g(x) is the set of all real numbers. Let f(x) = 3x + 5 and g(x) = x2. Find g(x) − f(x).
kifflom [539]

Answer:

3x^2 + 8  

Step-by-step explanation:

Given functions,

f(x) = 3x + 8 ----(1)

g(x) = x^2 -----(2)

Since,

(fog)(x) =  f( g(x) )      ( Composition of functions )

=f(x^2)             ( From equation (2) )

=3x^2 + 8          ( From equation (1) )

Hence,

(fog)(x)=3x^2 + 8
