Answer:
See Explanation Below
Explanation:
Your question isn't clear; However, I'll solve in two ways
1. Diameter = 14 cm
2. Radius = 14 cm
When Diameter = 14 cm
Given
![Area = \pi r^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/d8idhdkbvny3nuf23y6dswar31w3y3ic8z.png)
![Diameter = 14cm](https://img.qammunity.org/2021/formulas/mathematics/middle-school/pwj9razn21087hef2nobw3vwsocqql5mc6.png)
Required
Calculate the area of the circle
First, the radius has to be solved;
![Radius = (1)/(2) Diameter](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ibe47j8syxmcfncj2uvutxwngpbq8kdnhi.png)
![Radius = (1)/(2) * 14cm](https://img.qammunity.org/2021/formulas/mathematics/middle-school/qdjheaw0pv00128jjet9mowrl013eemgdp.png)
![Radius = 7cm](https://img.qammunity.org/2021/formulas/mathematics/middle-school/qkbxn31vhoqh6te44zidrbtgeipj4v9q6o.png)
Using the given formula;
The area is as follows
![Area = \pi r^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/d8idhdkbvny3nuf23y6dswar31w3y3ic8z.png)
![Area = 3.14 * 7^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/jb3ufhbbyap8h1lbs0sdwbbntcd35puqgc.png)
![Area = 3.14 * 49](https://img.qammunity.org/2021/formulas/mathematics/middle-school/grjfqdrp45yvj8pbkz64cyh8hcakqgq1c1.png)
![Area = 153.86cm^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/pcdl57m0hf8yn7c20k3ca7j0zb15i2rnua.png)
