The radius of a circle is 12 mm what is the circles area

Mathematics
2 answers:
Aleks04 [339]1 year ago
7 0

Answer:

Step-by-step explanation:

area of a circle = pi*r^2

pi = 3.14

r = 12 mm

area = 3.14 * (12)^2

area = 3.14 * 144mm

area = <u>452.16 mm^2 or 45.216 cm^2</u>

Hi student, let me help you out! :)

...........................................................................................................................................

We are asked to find the area of the circle.

\triangle~\fbox{\bf{KEY:}}

  • Use the formula:

\dag~\mathtt{A=\pi r^2}

Where:

A=Area

π=pi

r=radius (12 mm)

Have you noticed the ~^2 next to r? This tells us to multiply the radius times itself.

So, we substitute the values:

\mathtt{A=\pi (12)^2}

Square 12 first, then multiply:

\mathtt{A=144\pi }

Upon simplifying,

\dag~\underline{\mathtt{A=452.16\:mm^2}}

Hope it helps you out! :D

Write the equation of the line that passes through the points (-7, 7) and (-6, -5).
defon

Answer:

y = -12x - 77

Step-by-step explanation:

The standard form of the equation is expressed as y = mx+b

m is the slope

Given the coordinate (-7, 7) and (-6, -5).

m = -5-7/-6+7

m = -12/1

m = -12

Get the intercept b

Substitute m= -12 and (-7 7) into y = mx+b

7 = -12(-7) + b

7 = 84 + b

b = 7 - 84

b = -77

Get the required equation

y = mx+b

y = -12x +(-77)

y = -12x - 77

This gives the required equation

What is the domain and range of the relation shown in
Leya [2.2K]

Answer:

Domain : {10, 15, 19, 32}

Range: {-1, 5, 9}

Step-by-step explanation:

As the table of the relation is given as follows:

<em>X                Y</em>

<em>10               5</em>

<em>15               9</em>

<em>19               -1</em>

<em>32             5  </em>

From this table, we can define the relation by combining the ordered pairs from the table. Each and every order pair consists of x-coordinate and corresponding y-coordinate of any corresponding point.

So, the relation from the table can be made as follows:

                            relation : {(10, 5), (15, 9), (19, -1), (32, 5)}

Domain of a relation consists of all the x-coordinates (first elements) of order pairs.

Range of a relation consists of all the y-coordinates (second elements) of ordered pairs.

So, domain  and range of relation will be as follows:

                                  Domain : {10, 15, 19, 32}

                                  Range: {-1, 5, 9}

<em>Note: If there is any </em><em>duplicate</em><em> element in any x or y-coordinate of any ordered pair, it will be written only </em><em>once </em><em>when we determine domain and range. Here, in this example, 5 is duplicate, so, it will be mentioned only one time when we determine the range of this relation.</em>

Keywords:  domain, relation, range
