Answer:
See below :)
Explanation:
I'm not sure what kind of measurements they want or if it wants you to round up but I hope this helps
Ceiling fan: 17.584 ft
Water bottle cap: 81.64 mm
To get circumference from radius you can just do the radius times 2 and then that result times pi (3.14)
so for ceiling fan I did 2.8x2= 5.6 then 5.6x3.14= 17.584
Bowl: 8.996815287 cm
Drum: 12.00636943 in
To get radius from circumference you can do the circumference number divided by pi (3.14) to get your diameter. The diameter is twice the length of the radius so then you can just divide it by 2.
