The area of a circle is given with the following formula:
![A = \pi r^(2)](https://img.qammunity.org/2019/formulas/mathematics/high-school/h6o5tytci58l3vifztps7loi07tl4fjlsm.png)
A represents the total area of the circle, and r represents the radius of the circle.
We are given 5cm as our radius. Plug it into the equation:
![r = 5](https://img.qammunity.org/2019/formulas/mathematics/college/6kzptpjivm6hycvovpxocxmz691fzhnp94.png)
![A = \pi (5)^(2)](https://img.qammunity.org/2019/formulas/mathematics/college/95j9q9wcoupjzlr3idi9blpcsxdmid1587.png)
Solve the exponent:
![5^(2) = 25](https://img.qammunity.org/2019/formulas/mathematics/college/vwfodca5gafjqyqauhhpy4cli84f6cxsjf.png)
![A = 25\pi](https://img.qammunity.org/2019/formulas/mathematics/college/x12wvhn0nr12rl1bxjyieikiwyzv5tmsz4.png)
The answer is
B. 25π cm squared.
