What is the area of a circle that is 3 inches?

28.26 in²

Step-by-step explanation:

Radius = 3

Area = pi × r²

3.14 × 3²

28.26

28.27 inches^2

Step-by-step explanation:

The area of a circle can be found using:

a= pi* r^2

We know r, or the radius is 3, so we can substitute that in

a= pi * 3^2

a=pi *9

a=28.2743339...

The area is about 28.27 inches^2

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
