Answer:

22 square feet

Step-by-step explanation:

To find the area of a circle, you need to multiply pi times the radius squared. For the circular table with a diameter of eight, the radius is 4. When you square 4 and multiply it by pi, you will find that the area is approximately 50.27 square feet.

As for the area of the circular table with a diameter of 6, you can use the same strategy. The radius is half of the diameter, so 3. 3 squared times pi is approximately 28.27 square feet.

Then to find the difference you need to subtract the first area you found by the second are you found.

50.27 - 28.27 = 22 square feet

Answer:

22 ft^2

Step-by-step explanation:

The area of a table with diameter 6 ft

A = pi r^2 = pi (6/2) ^2 = pi 3^2 = 9pi

The area of a table with diameter 8 ft

A = pi r^2 = pi (8/2) ^2 = pi 4^2 = 16pi

Subtract 16pi-9pi = 7pi

Using 3.14 for pi

7 * 3.14

21.98 ft^2

To the nearest square foot

22 ft^2

Pani-rosa [81]

Bueno, usaré el español xD

11. Recordemos que entre más negativo es un número, menor es.

a) - 6 > - 10

ya que - 10 es más negativo, por consiguiente es menor, esto llega a confundir ya que tenemos la noción de que si vemos una cifra alta, por consiguiente es mayor, esto pasa en los positivos.

b) 12 > - 16

c) - 7 < 0

d) 35 > - 80

e) -37 < - 24

f) - 40 < 15

g) - 18 < 10

h) - 17 < 0

i) |-21| = |21|

El valor absoluto de un número negativo es su positivo, por lo que también puede ser:

21 = 21.

j) |176| > 0, o también 176 > 0

k) |-479| > |478|, o también 479 > 478

l) |-1375| = |1375|, o también 1375 = 1375

12. De menor a mayor.

a) - 8, - 7, - 4, 0, 3

b) - 16, - 12, - 7, 8, 9

c) - 15, - 13, 0, 9, 11

d) - 47, - 43, - 31, 14, 29

e) - 17, - 15, - 12, 16, 19

f) - 26, - 21, - 10, 17, 26

g) - 61, - 58, - 49, 30, 50

13. De mayor a menor.

a) 6, 4, - 1, - 5, - 7

b) 8, 0, - 7, - 11, - 13

c) 19, 6, - 8, - 10, - 17

d) 21, - 9, - 18, - 24, - 27

e) 53, 47, - 6, - 43, - 48

f) 14, 6, - 18, - 39, - 45

g) 24, 16, 12, - 12, - 17
