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
.
M + R + G = 119
G = 3M
M = R + 6 —> R = M - 6
1st equation: M + (M-6) + (3M) = 119
5M -6 = 119
5M = 125
M = 25
G = 3(25) = 75
R = (25) -6 = 19
