how many inches long is the radius of the largest circle that can fit inside a rectangle 18 inches long and 12 inches wide?
An 84cm wire is cut into three pieces. the second piece is 4 cm longer than the first piece and the third piece is twice as long as the second piece. find the lenght of the shortest piece.

The circle diameter cannot be greater than 12 inches.
S4=F
T=2S
T+S+F=84
2S+S+S4=84 solve for Second (S).
