Answer:
A =153.86
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
A = pi (7)^2
A = 49 pi
Letting pi be approximated by 3.14
A = 49 *3.14
A =153.86
Area of circle formula: A = πr^2
A = π(7)^2
A = π(49)
A = 153.86
Best of Luck!

Step-by-step explanation:
They are similar,
translation and rotation
Y=4x+19. To check your answer you can plug in the point (-4,3) into the equation to check your answer. Y=4x+19, 3=4(-4)+19, 3=3
What you do is add up all the values, then divide by the number of values.
The average of the data is
4.8575.
Plug g(x) in for every x in f(x) then substitute 4, you’ll get (f o g)(4) = 34
