The problem in the image describes a right-angled triangle with sides 6 cm, 8 cm, and 10 cm. The triangle is inscribed in a circle, meaning the circle is tangent to each side of the triangle. We are asked to find the radius of this circle.

This type of circle is known as the "incircle" of the triangle, and its radius can be determined using a specific formula for a right triangle. The formula for the radius \( r \) of the incircle of a right triangle with legs \( a \), \( b \), and hypotenuse \( c \) is:

\[
r = \frac{a + b - c}{2}
\]

### Given:
- \( a = 6 \, \text{cm} \)
- \( b = 8 \, \text{cm} \)
- \( c = 10 \, \text{cm} \) (the hypotenuse)

Now, substitute the values into the formula:

\[
r = \frac{6 + 8 - 10}{2} = \frac{4}{2} = 2 \, \text{cm}
\]

Thus, the radius of the circle is **2 cm**.

**Tip**: In any right triangle, the radius of the incircle can also give insight into the area of the triangle and help in solving various geometric problems efficiently.

Suatu segitiga siku-siku diposisikan sehingga beririsan dengan suatu lingkaran. Panjang sisi segitiga tersebut adalah 6 cm, 8 cm, dan 10 cm. Daerah di dalam lingkaran, tetapi di luar segitiga memiliki luas yang sama dengan daerah di dalam segitiga, tetapi di luar lingkaran. Panjang jari-jari lingkaran sama dengan … cm.

This problem involves a right triangle with sides 6 cm, 8 cm, and 10 cm, where the incircle touches all three sides. The task is to find the radius of the incircle. Using geometric formulas and the Pythagorean theorem, the radius is calculated to be 2 cm.
