Answer:
113.04 cm squared
Step-by-step explanation:
the area of a circle is:
A=πr2
so as you written before the pi must be 3.14
and the radius is the diameter/2(12/2=6)
A= 3.14 x 6 x 6
A= 113.04 cm squared
9514 1404 393
Answer:
0.28 -0.95i
Step-by-step explanation:

_____
<em>Additional comment</em>
If the original number is A∠β, the ratio is 1∠(2β), the square of the unit vector in the same direction as the original.
Given:
The vertices of ΔWXY are W(-10, 4), X(-3, -1), and Y(-5, 11).
To find:
Which type of triangle is ΔWXY by its sides.
Solution:
Distance formula:

Using distance formula, we get





Similarly,


Now,

So, triangle is an isosceles triangles.
and,





So, triangle is right angled triangle.
Therefore, the ΔWXY is an isosceles right angle triangle.
1) Add x to -2x, which is -x
2) Subtract 3 to 5, which is 2
