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

Explanation:

area = pi*radius*radius -> Radius =
`\sqrt{(area)/(pi) }`

area: 63.585 m2

-> radius =
`\sqrt{(63.585)/(3.14) }` = 4.5 m

area: 28.26m2

-> radius =
`\sqrt{(28.26)/(3.14) }` = 3m

-> diameter = 6m

area: 120.7016m2

-> radius =
`\sqrt{(120.7016)/(3.14) }` = 6.2m

-> diameter = 12.4m

area: 12.56m2

-> radius =
`\sqrt{(12.56)/(3.14) }` = 2m

area: 482.8064m2

->radius =
`\sqrt{(482.8064)/(3.14) }` = 12.4m

area: 113.04 m2

->radius =
`\sqrt{(113.04)/(3.14) }` = 6m
