To find the answer we can break the figure into two parts: a rectangle and a semi circle.

The perimeter of the rectangle:

(10+4)×2

=28 ft

The perimeter of the semi circle:

perimeter of a circle: 2×兀×radius

(The radius: 4/2)

We divide the perimeter by two as it is a semi circle,which is half the circumferece perimeter of a circle.

[2(3.14)(4/2)] / 2

=6.28 ft

We can then add up the numbers to find the answer, and remember that 4 cm is overlapped:

28+6.28-4

=30.28ft

Therefore the answer is 30.28ft.

Hope it helps!

Step-by-step explanation:

Recall that \frac{\sqrt{2} }{2} is a value of the function cosine for the special angles: 135^o and  225^o, then:

\frac{x}{2} =135^o\\x=270^o\\or\\ \frac{x}{2} =225^o\\x=450^o\\

Cuales son los terminos que siguen en cada sucesion:a)2,4,8,16,32,64,....B)1,3,5,7,9,....C)1,3,6,10,15,21,28,36,45
Elanso [62]

Answer:

a) Número siguiente = Número anterior * 2

b) Número siguiente = Número anterior + 2

c) Número siguiente = Número anterior + (n + 1)

Step-by-step explanation:

a) Para la secuencia 2,4,8,16,32,64, ....

El siguiente número es dos veces el número anterior.

Por ejemplo, 4 = 2 * 2, 8 = 4 * 2, 16 = 8 * 2 etc.

b) Para la secuencia 1,3,5,7,9, ....

El siguiente número es igual al número anterior + 2

Por ejemplo, 3 = 1 + 2, 5 = 3 + 2, 7 = 5 + 2 etc.

c) Para la secuencia1,3, 6,10,15,21,28,36,45

La diferencia entre los números aumenta en +1.

3-1 = 2

6-3 = 3

10-6 = 4

15-10 = 5

21-15 = 6

28-21 = 7
