Isosceles Triangle Inscribed Circle Perimeter Quiz

The perimeter of the triangle is 14 cm.

The area of the isosceles triangle is 6 square centimeters.

The formula for the area of an inscribed circle in a regular triangle is $A = \pi r^2$, where $r$ is the radius of the inscribed circle.

<p>The radius of an inscribed circle in a regular triangle is equal to the product of the side length of the triangle and the inradius (apothem) factor, which is $\frac{\sqrt{3}},{6}$.</p> Signup and view all the answers

<p>The side length of the regular triangle can be calculated using the formula $s = \frac{2A},{P}$, where $A$ is the area of the inscribed circle and $P$ is the perimeter of the triangle. In this case, the side length is $s = \frac{2 \times 12.56},{\pi \times \frac{s},{\sqrt{3}}}$.</p> Signup and view all the answers
