Well, you don't have any options.
But a mixed number for 12.16 would be 12 4/25. Hope it helps! :)
notice, if the original area was πr², then the new area has a factor in front of it, that much.
√196s² = √196 times √s²
s² is the square of 's'
196 is the square of 14
So both can easily come out of the radical.
√196s² = <u>14s</u>
Is 544 the answer I think or not
