Answer 1

Радиус вписанной окржуности r=3 cм Периметр P=20 см Полупериметр p=P\2=20 Площадь S=r*p=3*20=60 см^2 Отвтет: 60 см^2.

Answer 2

Problem Analysis

We are given that the radius of the circle inscribed in a triangle is 3, and we need to find the area of the triangle. To solve this problem, we can use the formula for the area of a triangle given its inradius (radius of the inscribed circle) and its perimeter.

Solution

The formula for the area of a triangle given its inradius (r) and its perimeter (P) is:

Area = (r * P) / 2 In this case, we are given that the radius of the inscribed circle is 3. However, we don't have the value of the perimeter of the triangle. Therefore, we need to find the perimeter of the triangle first.

To find the perimeter of the triangle, we can use the fact that the perimeter of a triangle is equal to the sum of the lengths of its sides. However, we don't have the lengths of the sides of the triangle either.

Since we don't have enough information to directly calculate the perimeter of the triangle, we need additional information to solve this problem.

Please provide the lengths of the sides of the triangle or any other relevant information that you have, and I will be happy to help you further.
