The area formula, A = tr2, would be used to find the area of a A. square.
B. rectangle.
O circle.
D. triangle
E parallelogram.

Assuming you meant to write , then the answer is C) circle

On your keyboard, you can say A = pi*r^2 to mean the same thing as above.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
