Question

The volume of a cylinder is 924x cm³ and height 6cm.Find its total surface area.​

Answer 1

Answer:

Solution:

The  volume  of  a  cylinder  =  924   cm^3

Height   of  a  cylinder  = 6 cm

Total  surface  area  =  ?

The  volume  of  a  cylinder=πr2h

πr2h=924

22/7 * r * 6 = 924

r=924/6*7/22=154*7/22=49

Total surface area  =   2πr(h + r)

                                = 2*22/7* 7 (6+7)    

                                = 2*22/7*7*13

                                 =44*13

                                 =572 cm ^2
