At the car show Inez saw a truck wheel shaped like a circle with a radius of 3 ft. She wants to know the area of the truck wheel
Nadusha1986 [10]

Answer:

28.27ft^2

Step-by-step explanation:

To solve this problem, we can use the area of a circle formula:

A=\pi r^2

<em>A = area</em>

<em>r = radius</em>

Lets plug the values into the equation:

A=\pi (3^2)     Calculate 3^2

A=\pi (9)       Multiply \pi and 9 together

A=28.27

The area of the truck wheel is 28.27ft^2

Can someone explain thoroughly how I am meant to solve this?
BartSMP [9]

Answer:

I got x<equal to -11 or x>equal to4

Step-by-step explanation:

x^2+15x+44=0

(x+4)(x+11)=0(Factor left side of equation)

x+4=0 or x+11=0(Set factors equal to 0)

x=−4 or x=−11

Check intervals in between critical points. (Test values in the intervals to see if they work.)

x<−11(Works in original inequality)

−11<x<−4(Doesn't work in original inequality)

x>−4(Works in original inequality)

Answer:

x<−11 or x>−4
