Q. No,
Find the area of metal sheet required
to prepare 50 circular cylindrical closed boxes having radius 10 cm and height 15 cm
(π= 3.14)​

Answer 1

Answer:

78500

Step-by-step explanation:

area of metal sheet = 50*{2πrh +2πr∧2}

                                    50*[2πr{h+r}]

                                    50*[2*3.14*10{15+10}]

                                    50*[2*31.4*25]

                                    50*[5*314]

                                   1570*50

                                   78500 cm∧2
