To find the area of the incircle of a triangle, you can use the formula:

[ \text{Area of incircle} = \pi r^2 ]

where ( r ) is the radius of the incircle.

The radius of the incircle ( r ) can be found using the formula:

[ r = \frac{\text{Area of the triangle}}{\text{Semiperimeter of the triangle}} ]

The semiperimeter of the triangle is given by:

[ s = \frac{AB + BC + AC}{2} ]

Given the vertices of the triangle and the angles at those vertices, you can find the lengths of the sides of the triangle using the Law of Sines or other trigonometric relationships.

Once you have the lengths of the sides of the triangle, you can calculate the semiperimeter ( s ), and then find the radius of the incircle ( r ). Finally, use the formula for the area of the incircle to find the area.

If you provide the lengths of the sides of the triangle, I can help you calculate the area of the incircle.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
