Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Match each area to its corresponding radius or diameter of the circle.(All areas are approximate.)

Please give me answer

The answer is B. 27.318

Step-by-step explanation:

The formula for the circumference is , where r is the radius of the circle. Because we know that the radius is half of the diameter, which we're given, we'll have to divide the diameter by 2 to get this. Our equation would then become . However, because we're dividing by 2 and multiplying by two, these two cancel each other out, so the equation for circumference may also be written as , where d is the diameter.

Now we solve (where pi is simplified to equal 3.14):

C=27.318 cm.

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)
