A cylindrical tank has a capacity of 3080 m3. What is the depth of the tank if the diameter of its base is 14 m? (Take pi = 22/7)
A.
23 m
B.
25 m
C.
20 m
D.
22 m
Correct Answer: 20 m
Explanation
Capacity = 3080 m3 Base diameter = 14 m, thus radius = 7 m. Volume of cylinder = capacity of cylinder = πr2h. = 3080 22/7 x 72 x h = 3080 h = 3080/(22x7) h = 20 m
Capacity = 3080 m3 Base diameter = 14 m, thus radius = 7 m. Volume of cylinder = capacity of cylinder = πr2h. = 3080 22/7 x 72 x h = 3080 h = 3080/(22x7) h = 20 mTHIS WEEK's
