Answer:
excusme where is the model
Step-by-step explanation:
the area A of the cross section of the column is
.
<u>Step-by-step explanation:</u>
Here we have , building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18π, pi meters. We need to find What is the area A of the cross section of the column .Let's find out:
We know that , Circumference of circle = 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
We know that area of circle = 
⇒ 
⇒ 
⇒ 
Therefore , the area A of the cross section of the column is
.
The ratio would be 6:1 because out of every 6 people, 1 person got a role. Please mark Brainliest!!!
Answer:
x^2 -10x -96 =0
Step-by-step explanation:
Subtract the zeros from x in factors
(x - -6) (x-16)
(x+6) (x-16)
Set these equal to zero since they are zeros
(x+6) (x-16) =0
FOIL
x^2 -16x+6x -96 =0
x^2 -10x -96 =0
