Step-by-step explanation:
The area of the shaded sector is one-fourth of the area of the whole circle so:

area of shaded region

The area of the shaded region is 9pi units^2
First, you need to make sure that they're in the same measurement ration
1 m = 100 cm
so, now you have
73 cm + 160 cm + 287 cm + 325 cm + 404 cm
The total length would of all the wood would be be 1249 centimeters or 12.49 meter
