Answer:
See Explanation Below
Step-by-step explanation:
Your question isn't clear; However, I'll solve in two ways
1. Diameter = 14 cm
2. Radius = 14 cm
<em></em>
<em>When Diameter = 14 cm</em>
Given
![Area = \pi r^2](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20r%5E2)
![Diameter = 14cm](https://tex.z-dn.net/?f=Diameter%20%3D%2014cm)
Required
Calculate the area of the circle
First, the radius has to be solved;
![Radius = \frac{1}{2} Diameter](https://tex.z-dn.net/?f=Radius%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20Diameter)
![Radius = \frac{1}{2} * 14cm](https://tex.z-dn.net/?f=Radius%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%2014cm)
![Radius = 7cm](https://tex.z-dn.net/?f=Radius%20%3D%207cm)
Using the given formula;
The area is as follows
![Area = \pi r^2](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20r%5E2)
![Area = 3.14 * 7^2](https://tex.z-dn.net/?f=Area%20%3D%203.14%20%2A%207%5E2)
![Area = 3.14 * 49](https://tex.z-dn.net/?f=Area%20%3D%203.14%20%2A%2049)
![Area = 153.86cm^2](https://tex.z-dn.net/?f=Area%20%3D%20153.86cm%5E2)
<em>When Radius = 14 cm</em>
Given
![Area = \pi r^2](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20r%5E2)
![Radius = 14cm](https://tex.z-dn.net/?f=Radius%20%3D%2014cm)
Required
Calculate the area of the circle
Using the given formula;
The area is as follows
![Area = \pi r^2](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20r%5E2)
![Area = 3.14 * 14^2](https://tex.z-dn.net/?f=Area%20%3D%203.14%20%2A%2014%5E2)
![Area = 3.14 * 196](https://tex.z-dn.net/?f=Area%20%3D%203.14%20%2A%20196)
![Area = 615.44cm^2](https://tex.z-dn.net/?f=Area%20%3D%20615.44cm%5E2)
Adding even integer numbers will always give you an even integer number, so they cannot equal 163.

if you have already covered slopes, you could also get it that way, in fact is simpler that way.
