Four circles, each with a radius of 2 inches, are removed
from a square what is the remaining area of the square?
(16 - 4rt) in
(16 - 1) in 2
(64 - 167) in
(64 - 417) in

The remaining area of the square

Step-by-step explanation:

Step 1: Finding the area of the Square

Radius of the circle is 2m.

So using the radius we could find the side of the square

=>side of the square  = 4(radius of the square)

=>side of the square  = 2(diameter of the square)

=>side of the square  = 2 x (4 inches)

=>side of the square  = 8 inches

Now area of the square=

=>

=>

Area of the square=

Step 2: Finding the area of the circle

Area of a circle=

=>

=>

Area of a circle=

Now area of 4 circle =

=>

Area left when 4 circles removed from the square = area of the square - area of four circles

=>  

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

x = 3 ± √(5+y)
