Find the area of the figure. PLEASSEEEEEEEE!!!!!!!!
allochka39001 [22]

Given:

side length = 6 ft

To find:

The area of the figure

Solution:

Area of the square = side × side

                               = 6 × 6

Area of the square = 36 ft²

Diameter of the semi-circle = 6 ft

Radius of the semi-circle = 6 ÷ 2 = 3 ft

Area of the semi-circle = \frac{1}{2} \pi r^2

                                      $=\frac{1}{2} \times 3.14 \times 3^2

Area of the semi-circle = 14.13 ft²

Area of the figure = Area of the square - Area of the semi-circle

                              = 36 ft² - 14.13 ft²

                              = 21.87 ft²

Area of the figure = 21.9 ft²

The area of the figure is 21.9 ft².

al dividir A entre 23 se obtuvo 247 de cociente y el residuo fue el maximo. hallar A a)5242 b)5436 c)5703 d)5332 solo esas 4 alt
yuradex [85]

Aplicando la división, hay que el valor de A es dado por:

c) 5703

Una división es representada por:

\frac{a}{b} = c + \frac{r}{b}

En que:

  • c es el cociente.
  • r es el residuo.

En este problema, b = 23, y también:

  • Cociente de 247, o sea, c = 247.
  • Residuo maximo, que es 22, o sea, r = 22.

\frac{a}{b} = c + \frac{r}{b}

\frac{A}{23} = 247 + \frac{22}{23}

A = 23(247) + 22 = 5703

El valor de A es dado por:

c) 5703
