What is the capacity of the cylindrical tank?

I.

The area of the base is 61,600 sq. cm.

II.

The height of the tank is 1.5 times the radius.

III.

The circumference of base is 880 cm.

A. Only I and II
B. Only II and III
C. Only I and III
D. Any two of the three
E. Only II and either I or III

• Capacity = pi r2h. (where pi=22/7=3.1416)
  
  I gives,pi r2 = 61600. This gives r.
  
  II gives, h = 1.5 r.
  
  Thus, I and II give the answer.
  
  Again, III gives pi2r = 880. This gives r.
  
  So, II and III also give the answer.
  
  and so Only II and either I or III is the answer

• it should be I and II or II and III bcoz I or III gives only radius.
  only II doesn't gives exact value.

• Area Of Cylindrical Tank = πr²h
  Circumference = 880 = 2πr
  → πr=440
  → r = 140 cm
  → h = 210 cm
  Now on putting Values in πr²h we will get the answer
  So, II and III give the answer
