Question

Длина стороны квадрата рисунок 105 равна 4 сантиметра найдите с точностью до 0,1 в сантиметры в квадрате площадь закрашенной фигуры (задача 622 страница 189 учебник математики муравина 6 класс) от Maksimenko1944.

Answer 1

♣1 ая фигура будет S квадрата + 2Sокуж
S кв = 4×4 = 16 см²
Sо = πR² = 3.14×4 = 12.56 cм²
S ф1 = 16 + 2×12,56 = 41,12 см²♣

Answer 2

Finding the Area of the Shaded Figure

To find the area of the shaded figure in the given problem, we need to determine the length of the side of the square and then calculate the area.

The problem states that the length of one side of the square is 4 centimeters and the total perimeter of the figure is 105 centimeters. We can use this information to find the length of the other sides of the figure.

Let's start by finding the perimeter of the square. Since a square has four equal sides, the perimeter is calculated by multiplying the length of one side by 4:

Perimeter of the square = 4 * 4 = 16 centimeters.

Now, we know that the total perimeter of the figure is 105 centimeters. Since the square accounts for 16 centimeters of the perimeter, we can subtract that from the total to find the perimeter of the shaded figure:

Perimeter of the shaded figure = Total perimeter - Perimeter of the square = 105 - 16 = 89 centimeters.

Since the shaded figure is made up of four equal sides, we can divide the perimeter by 4 to find the length of one side of the shaded figure:

Length of one side of the shaded figure = Perimeter of the shaded figure / 4 = 89
