The perimeter of the circle is 18.84 miles and area of the circle is 28.26 miles square.

<h3>What is the perimeter of the circle?</h3>

The perimeter of the circle that has a radius of r is defined as the product of diameter to the pie value.

The perimeter of the circle = 2πr

The perimeter of the circle = 2 (3.14) (3)

The perimeter of the circle = 18.84 miles

Also,

The area of the circle =πr^2

= 3.14 (3)^2

= 28.26 miles square

What is the distance between (–4, –10) and (–4, –4)?

Gre4nikov [31]

Answer:

6 units

Step-by-step explanation:

(-4 , -10) ; (-4 , -4)

Distance = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

$= \sqrt{(-4-[-4])^{2}+(-4-[-10])^{2}}\\\\= \sqrt{(-4+4)^{2}+(-4+10)^{2}}\\\\=\sqrt{0+(6)^{2}}\\\\= \sqrt{36}\\\\= 6$

noname [10]

1790988582563.6448is your answer. All you do is multiply 14 times 1.2, which equals 16.8. Then you do 16.8 times itself. 16.8 x 16.8 = 282.24. Then 282.24 times itself, and so on so forth.
