Answer: 907.92 ft²
Explanation:
1. To solve this problem you must apply the formula for calculate the area of a circle, which is shown below:
![A=r^(2)\pi](https://img.qammunity.org/2020/formulas/mathematics/middle-school/y5r162f9g641qgu6hzv9h22tnd6zc66cfo.png)
Where r is the radius of the circle.
2. You know the radius of the circle B, therefore, when you susbtitute it into the formula, you obtain that the area of the circle B is:
![A_B=(17ft)^(2)\pi=907.92ft^(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/47mx5ritxpi8orugmy1gpm2twe4l9b4h5w.png)
