Grade 7 - Quarter 3 - Week 7
The center of a circle is
located at (3,-4) and the
end of a radius is located at
(-1,-4). What is the area of
the circle?
How do you solve? What formula do you use?

Respuesta :

Answer:

The area of the circle is around 50.24

Step-by-step explanation:

The formula for the area of a circle is [tex]\pi r^{2}[/tex]

To find r, we can use the point that is given to us. To find the distance of the radius, we can use the formula

[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]

We can just plug in the points given into the formula and we get,

4.

Now we can plug 4 into the formula

[tex]\pi r^{2}[/tex]

[tex](3.14)(4^{2})[/tex]

Resulting in,

around 50.24.
