The complete question is: Henry knows that the circumference of a circle is
18π inches. What is the area of the circle?
Solution:Circumference (C) of the circle can be written as:
![C=2 \pi r \\ \\ 18 \pi =2 \pi r \\ \\ r=9](https://tex.z-dn.net/?f=C%3D2%20%5Cpi%20r%20%5C%5C%20%5C%5C%2018%20%5Cpi%20%3D2%20%5Cpi%20r%20%5C%5C%20%5C%5C%20r%3D9)
Using this value of radius, we can find the Area(A) of the circle.
Therefore, area of the circle having a circumference of 18π inches will be 81π inches²
It’s equal to 1
2x divide by 2x = 1

Answer:
k = 28
Step-by-step explanation:
12/k = 18/42
Cross multiply.
18k = 12 * 42
18k = 504
Divide both sides by 18.
k = 28
