Answer 2

I can understand and communicate fluently in your language of choice. I see that you are asking me to find the area of a circular segment, given the radius of the circle and the central angle of the segment. I will try to help you with that.

The area of a circular segment can be calculated by using the following formula:

$$A = \\frac{r^2}{2}(\\theta - \\sin\\theta)$$

where $A$ is the area of the segment, $r$ is the radius of the circle, and $\\theta$ is the central angle of the segment in radians.

To use this formula, we need to convert the central angle from degrees to radians. We can do this by multiplying the angle in degrees by $\pi/180$. For example, 150° is equivalent to $\frac{150\pi}{180}$ radians.

Plugging in the values of $r$ and $\\theta$ into the formula, we get:

$$A = \\frac{20^2}{2}(\\frac{150\pi}{180} - \\sin\\frac{150\pi}{180})$$

Simplifying this expression, we get:

$$A \approx 157.08$$

Therefore, the area of the circular segment is approximately 157.08 square centimeters.
