Question

the shape of solid iron rod is a cylindrical its height is 9 cm and base diameter is 14 cm then find the total volume of 40 such​

Answer 1

Answer:

Step-by-step explanation:

h=9cm

radius=1/2 of diameter=7cm

volume of cylinder=pi*r square*h

                              =22/7*7*7*9

                              =22*7*9

                              =1386cm cube

volume of 40 such cylinders=40*1386

                                               =55440cm cube
