What is the circumference of a round pizza with an area of 36 square inches ? step by step like can anyone explain to me in words

The circumference of the round pizza is 21.26in

Step-by-step explanation:

To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of area of a circle and we will clear the radius

a = area = 36in²

r = radius

π = 3.14

a = π * r²

we clear r

r = √(a/π)

now we replace the known values

r =  √(36in²/3.14)

r = √(11.46in²)

r = 3.385 in

now we use the formula to calculate the circumference of a circle

c = π * 2r

c = 3.14 * 2 *  3.385 in

c = 21.26in

The circumference of the circle is 21.26in

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

a. positive: 2 or 0; negative : 2 or 0; complex: 4or2or0
