Responder:

2 1/4 m; 225 cm

Explicación paso a paso:

Dado:

Cortar 9 metros en 4 partes de la misma longitud;

Por lo tanto,

9 metros / 4

= 2,25 metros

Por lo tanto, cada varilla será 2.25 = 2 1/4 m

En cm;

1 m = 100 cm

2,25 metros = x

x = 100 * 2,25

x = 225 cm

The circumference of a circle is 23π m. What is the area, in square meters? Express your answer in terms of \piπ
LenaWriter [7]

Answer:

Area of the circle =   \frac{529}{4}  π  m²    or      132.25 π  m²

Step-by-step explanation:

To find the area, we will follow the steps below.

First write down the formular for the circumference of a circle, then use the formula to find the radius of the circle after which you can now find the area of the circle.

That is;

C = 2πr

where c is the circumference of the circle and   r is the radius of the circle

From the question given, circumference C = 23π

23π = 2π r

Divide both-side of the equation by 2π

23π/2π  =  2πr/2π

23/2   =  r

radius =   \frac{23}{2}  m

Formula for calculating the area of a circle is given by;

A = πr²

where A= area of the circle   and   r is the radius of the circle

A = π ( \frac{23}{2} )²

A = \frac{529}{4}  π  m²    or      132.25 π  m²

Area of the circle =   \frac{529}{4}  π  m²    or      132.25 π  m²

Convert 1.50 micrometers^2 to m^2. Show your solution.
Vadim26 [7]

Here is the solution for the problem:

<span>1m * 1m = 1m² </span><span>
<span>1m = 1,000,000µm = 1 x 10^6µm </span>
<span>1 x 10^6µm * 1 x 10^6µm = 1m² </span>
<span>1x10^12µm² = 1m² (Now, divide both sides by 1x10^12). </span>
<span>1x10^12µm² / (1 x 10^12) = 1m² / (1 x 10^12) </span>
<span>1µm² = 0∙000 000 000 001 m² (x both sides by 1.5). </span>
<span>1.5µm² = 0∙000 000 000 0015 m² </span>
1.5µm² = 1∙5x10^-12 m²</span>

So 1.50 micrometers^2 is equal to 1.5 x 10^-12 m². I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
