The area of an exercise aid that is textured from the information regarding Fiona is 50 inches².
<h3>How to calculate the area?</h3>
From the information given, the measures or the exercise aid is approximately 25 inches around its base. Therefore, the radius will be calculated thus:
2πr = 25
(2 × 3.142 × r) = 25
6.284r = 25
r = 25/6.284
r = 3.978 = 4
Therefore, the area will be:
= πr²
= 3.142 × 4²
= 50 inches²

To find CD use the trig ratio that relates that side you're looking for to the angle you have and the other side you're given. We have that the reference angle is 30, and we also have the hypotenuse of that right triangle on the left. Solving for AC, which is the side opposite, we will use the sin ratio:
![sin(30)= \frac{AC}{10}](https://tex.z-dn.net/?f=sin%2830%29%3D%20%5Cfrac%7BAC%7D%7B10%7D%20)
. 10 sin(30) = AC. Therefore, AC = 5. Now that have that side measure, we can use that along with the reference angle in the right triangle on the right of 25 to find CD, which happens to be the side adjacent to the reference angle. That satisfies our tangent ratio requirements. Our ratio looks like this then:
![tan(25)= \frac{5}{CD}](https://tex.z-dn.net/?f=tan%2825%29%3D%20%5Cfrac%7B5%7D%7BCD%7D%20)
. Solving for CD,
![CD= \frac{5}{tan(25)}](https://tex.z-dn.net/?f=CD%3D%20%5Cfrac%7B5%7D%7Btan%2825%29%7D%20)
and CD = 10.7, the third choice above.
