Question

Find the volume, Curved Surface Area and Total Surface Area. A metallic cylinder with base radius 2. 8cm and height is 12 cm. Also find its width if the metal weight 20gram per cm^3

Answer 1

Answer:  

    curve surface   = 2\pi*r*h

            = 2*22/7*2.8*12

            =211.2 cm^2

      volume= \pi*r^2*h

                   =22/7*(2.8)^2 *12

                   =295.68 cm^3

       total surface area= 2\pi*r*h+2*\pi*(r)^2

                                    =2*22/7*2.8*12+2*22/7*(2.8)^2

                                    = 5253.24 cm^2

         

Answer 2

Answer:

Volume of the cylinder =295.68cu.cm

Total surface area of cylinder =260.48sq.cm

Curved surface area of cylinder =211.2 sq.cm
