Answer:
14 inch
Step-by-step explanation:
A = πr^2
153.94 = π * r^2
153.94/π = 49.001 = r^2
√49.001 = r = 7
radius * 2 = diameter
7 * 2 = 14 inch diameter
Uhh my brains hurts looking at that

Answer:
The longer piece: 54m
The shorter piece: 19m
Step-by-step explanation:
Make an equation from what is said.
One of the pieces is 'x'
The other piece is 2x+16
x + (2x + 16) = 73m
solve for x
x = 19
plug it in
2*19 + 16
you get 54
so 54 is the longer piece
and 19 is the shorter piece (x was the shorter piece)
Hope this helped :)
