Answer:

Given: Diameter of base of cylinder =14 cm.

∴ Radius (r)=214=7 cm.

and Height of cylinder is h=20 cm.

So, Surface area of cylinder =2πr(r+h)

                                               

                                                =2×722×7(7+20)

                                                

                                                =44×27

 Surface area of cylinder =1188 sq.cm.

Volume of cylinder =πr2h

                                =722×72×20

                                =22×7×20

Volume of cylinder=3080 cu.cm
