  2. Whatis the ratio of surfacearea of cylinderA to cylinderB?

  3. Whatis the ratio of the volumeof cylinderB to cylinderA?


Answers



  1. The volumewill be 64 timesgreater. Volume= s^3 New volume= (4s)^3

  2. Volumewill be 8 timesgreater.

  3. The volumewill be 8 timesgreater(2w)(2l)(2h)= 8 wlh = 8 (volumeof first rectangularsolid)


4. 5^3 /9^3

5. 4/9


  1. All spheresand all cubesare similarsinceeachhas only one linearmeasure.All cylindersare not similar.
    Theycan only be similarif the ratio of the radii = the ratio of the heights.

  2. 60 cm

  3. 20/5 = 4/1

  4. 16/1


10. 1/4^3
