Question

what is the radius of a kitchen table with a circumfrence of 19.79 feet ?.......... use pi=3.14.............round ur answer to the nearest hundred

Answer 1

\[Circumference = 2 \pi r\]
\[19.79 = 2 \pi r\]
\[r = (19.79)/(2 \pi)\]
\[Area = \pi r^{2}\]
\[Area = \pi (19.79/(2 \pi))^{2} = 31.18\]

Answer 2

Woops stepped past the radius
\[r = 3.15 ft\]
