5.86 cm.

Step-by-step explanation:

First, we can find the area of the circle:

π · 1² = 1π or just π.

Next, we can find the area of the rectangle without the circle:

3cm · 3cm = 9cm total for our area. (without circle inside).

Now we can subtract pi from our answer 9 cm.

That gives us 5.85840734641

Since this once it to the nearest hundredth, we round:

5.86 because 8 is our determining digit.

So 5.86 is our answer

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
