Answer:
<em>u</em> = 7.21
Step-by-step explanation:
The magnitude of <em>u</em> is just the distance between the two points. The coordinates of the left-most point are (-2,-8) and the coordinates of the right point are (4, -4). I'm assuming the x coordinates here because we don't actually know the scale.
Ok so from these points, you can draw a triangle (u can see it in the attached file).
From the coordinates we can tell the lengths of the sides, and the triangle shows that <em>u</em> is the hypotenuse of the triangle. This triangle is also a right triangle, so u can use Pythagoras' theorem to find the length of <em>u</em>.
Since c = <em>u</em>, we know now that the magnitude of <em>u</em> is 7.21

- The equation of a circumference is
. - Then , in this case
, and then to know the value of r we just simply have to calculate the square root of 9, which is 3.
Answer:
The perfect square of 3*4 is 9*16
Step-by-step explanation:
A perfect square is a number that can be expressed as the product of two equal integers.
For example 64 is a perfect square because if we multiply 8 two times we will get 64.
Thus the given expression is 3 * 4.
To find perfect square we square the numbers:
3² = 3*3 = 9
4² = 4*4 = 16
Thus the perfect square of 3*4 is 9*16 ....
