Find the area of a circle that measures 8 cm from the center to the edge. Use 3.14 for π.

Area of the circle =25.12 cm ^2

Step-by-step explanation:

So, we have 8 cm as a diameter.

So, Radius will be half of it i.e 4 cm.

Now, Area of circle = pir^2

= 3.14 * 4* 2

= 25.12 cm ^2

Hope it helps!

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)
