6

Step-by-step explanation:

The circumference of a circle is 2*pi*radius. You can multiply 2 by pi and then divide the circumference by that number to get the radius.

2 * 3.14 = 6.28

37.7/6.28 = 6.00318471, which rounds down to 6 in.

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)
