Question

A tank in the shape of a cylinder of diameter 2.4 M and the height 6.4 M contain oil up to the brim find the number of complete cylinder container of base radius 8.2 cm and height 28 CM that can be filled by the oil in the tank​

Answer 1

Answer:

Step-by-step explanation:

Volume of the cylindrical portion of the tank= TTr2h

=22/7 * (21/2)2 * 18cm3 = 174636/ 28 cm3

= 6237cm3

Volume of 2 conical ends

=2 (1/3 TTr2h) =2/3 TTr2h =2/3 * 22/7 * (21/2)2 * 9cm3

=174636 / 84 cm3 =2079cm3

Therefore, capacity of the tank= 6237cm3 + 2079cm3= 8316cm3

Thus, capacity of the tank= 8316cm3

Answer 2

Answer:

Step-by-step explanation:

volume of the cylindrical portion of the tank= ttr²h

=22/7 * (21/2)2 * 18cm3 = 174636/ 28 m3

= 6237m3

volume of 2 conical ends

=2 (1/3 ttr2h) =2/3 ttr2h =2/3 * 22/7 * (21/2)2 * 9m3

=174636 / 84 m3 =2079m3

therefore, capacity of the tank= 6237m3 + 2079m3= 8316m³=83160000

thus, capacity of the tank= 8316m³
