Question

the volume of a cylinder is 448 cm cube one height is 6 cm find its lateral surface area and total surface area

Answer 1

Answer:

volume of cylinder =$\pi r^{2} h$

                               = 22/7*r*r*6 = 448

                               = 132*r*r = 3136

                               = r*r = 3136/132

                               = r*r = 23.75

                               = r = 4.87cm

lateral surface area = 2*22/7*4.87*6

                                 = 183.59 cm

total surface area = 2*22/7*4.87(4.87+6)

                             = 332.61 cm cube
