Question

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

Answer 1

Answer:

Step-by-step explanation:

area = pi*radius*radius -> Radius =  $\sqrt{\frac{area}{pi} }$

area: 63.585 m2

   -> radius = $\sqrt{\frac{63.585}{3.14} }$ = 4.5 m

area: 28.26m2

  -> radius = $\sqrt{\frac{28.26}{3.14} }$ = 3m

   -> diameter = 6m

area: 120.7016m2

  -> radius = $\sqrt{\frac{120.7016}{3.14} }$ = 6.2m

   -> diameter = 12.4m

area: 12.56m2

   -> radius = $\sqrt{\frac{12.56}{3.14} }$ = 2m

area: 482.8064m2

   ->radius = $\sqrt{\frac{482.8064}{3.14} }$ = 12.4m

area: 113.04 m2

   ->radius = $\sqrt{\frac{113.04}{3.14} }$ = 6m
