Surface Area of Cylinders


Group Results of Cylinder having Surface Area of 900 cm² 

Radius Height
cm
Volume
 cm³
Surface Area
cm²
Ratio Surface Area/Volume
cm²/cm³ 
2 70 879.2 904.32 1.03
3 45 1271.7 904.32 0.71
5 24 1884 910.6 0.48
9 7 1780.38 904.32 0.51
10 4 1256 879.2 0.70

  1. What things stand out about the data displays?
  2. Compare the relationship between radii and heights.  
  3. Predict the size other radius/height pairs that fit the pattern. 
  4. What are some further questions for this investigation?
