Answer:
81pi meter squared
81π m²
Step-by-step explanation:
Formula: C=2πr
The circumference of the column is 18π meters so therefore: 18π=2πr
Divide the both sides by 2π:
r= 9 meters
Now find the area:
Formula for Area: A=πr²
Therefore: A= π · 9² = 81π meters²
that is the solution to the question
2+0.15x=3.20
So you have the original or starting point $2 which b in y=Mx+b then it’s 0.15 per day but you don’t know how many days so you use x and she owed a total of 3.20
