Question

two types of water tankers are available in shop at same cost.one is in a cylindrical form of diameter 3.5m and height 2m and another is in the form of a sphere of diameter 3m.calculate the volume of both tankers.the shopkeeper advices to purchase cylindrical tanker.what value is depicted by the shopkeeper

Answer 1

volume of cylinderical tank=πr²h
=22/7*3.5*2=22m³
volume of sphere=(a)³=(3)³=27m³

Answer 2

Answer:

Volume of cylinder = $19.242 m^3$

Volume of sphere = $14.1371$  

Step-by-step explanation:

Diameter of cylinder = 3.5 m

Radius of Cylinder = $\frac{Diameter}{2}=\frac{3.5}{2} =1.75 m$

Height of cylinder = 2 m

Volume of cylinder = $\pi r^2h$

                                = $3.14 \times (1.75)^2 \times 2$

                                = $19.242 m^3$

Diameter of sphere = 3 m

Radius of sphere = 1.5 m

Volume of sphere = $\frac{4}{3} \pi r^3$

                               = $\frac{4}{3} \times 3.14 \times (1.5)^3$  

                               = $14.1371$  

Thus the volume of cylinder is larger than the volume of sphere while their costs are same.So, That's why he shopkeeper advice to purchase cylindrical tanker
