Question

A metal cuboid of dimension 22 cm
x 15 cm. * 7.5 cm. was melted and cast into a cylinder of height 14cm. what is radius​

Answer 1

Answer:

radius = 7.5 cm $\pi$

Step-by-step explanation: volume of cuboid = volume of cylinder

                                            l x b x h =  $\pi$ x r^2 x h

                                             22 x 15 x 7.5 = 22/7 x r^2 x14

                                            2475 cm^3 = 44 x r^2

                                           r =  (2475/44)

                                           r = 7.5 cm
