Match each area of a circle to its corresponding radius or diameter. area: 63.585 square meters area: 28.26 square meters area: 120.7016 square meters area: 12.56 square meters area: 482.8064 square meters area: 113.04 square meters diameter: 12.4 meters radius: 4.5 meters diameter: 6 meters radius: 2 meters

Step-by-step explanation:

area = pi*radius*radius -> Radius =  

area: 63.585 m2

   -> radius = = 4.5 m

area: 28.26m2

  -> radius = = 3m

   -> diameter = 6m

area: 120.7016m2

  -> radius = = 6.2m

   -> diameter = 12.4m

area: 12.56m2

   -> radius = = 2m

area: 482.8064m2

   ->radius = = 12.4m

area: 113.04 m2

   ->radius = = 6m

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)
