This composite shape is a rectangle with a semicircle attached on one end. The diameter of the semicircle is 6 feet.
Ugo [173]

As we can see on the picture we have a rectangle and half of circle.

The areas for half circle and rectangle are:

A_{rectangle}=a\cdot b \\A_{halfcircle}=\frac{A_{circle}}{2}=\frac{\pi r^2}{2}

The area of the figure is the sum of the area of half circle and rectangle. Also the height of a rectangle (6ft) is a diameter of a half circle therefore the radius of half circle is 6ft ÷ 2 = 3ft.

Now we calculate the areas.

A_{rectangle}=10\cdot 6=\underline{60} \\A_{halfcircle}=\frac{3.14\cdot3^2}{2}=\underline{14.13} \\A_{total}=A_{rectangle}+A_{halfcircle} =60+14.13=\boxed{74.13\approx74}

The area of the figure is approximately 74ft squared.

Hope this helps.

Find the Measure of angle O<br> (see image)<br> Only real answers, please
-Dominant- [34]

Answer:

From the given figure we can see that :---

MN||PO, MN=PO and MP=NO

Therefore, angle M=angle N (adjacent sides of the trapezoid)

(8x - 16)  =  (6x + 20) \\ 2x = 36 \\  \boxed{x = 18}

angle M=angle N= (6×18)+20=108+20 =128°

angle O =(180°-128°)=52°

<h3>Hence, angle O is <u>52°.</u></h3>

Descubriendo los triples pitagóricos – Explicado

El Teorema de Pitágoras es ciertamente uno de los teoremas más famosos en todas las matemáticas. Tanto los matemáticos como los laicos lo han estudiado durante siglos, y la gente lo ha demostrado de muchas maneras diferentes. (Incluso al presidente James Garfield se le atribuyó una prueba nueva y original.) Así que sin más preámbulos, aquí está:

El Teorema de Pitágoras: La suma de los cuadrados de las piernas (los dos lados más cortos) de un triángulo recto es igual al cuadrado de la hipotenusa (el lado más largo).

Si usted escoge cualquier número antiguo para dos de los lados de un triángulo rectángulo, el tercer lado usualmente termina siendo irracional – usted sabe, la raíz cuadrada de algo. Por ejemplo, si las patas son 5 y 8, la hipotenusa termina siendo la raíz cuadrada de 89, o aproximadamente 9.43398 ….. (el decimal continúa para siempre sin repetirse). Y si escoges números enteros para la hipotenusa y una de las patas, la otra pata suele terminar siendo la raíz cuadrada de algo.

Can someone explain how you find the slope of stairs
Rina8888 [55]

Answer:

Measure the distance of treads (Exclude the width of nosing). If all the treads are uniform in size, measure one tread otherwise you will need to measure all treads. ...

Measure the height of risers. ...

Divide the riser height by the tread width and then calculate the inverse tangent.
