Answer 2

Answer:

2153 cm2

Step-by-step explanation:

r=14cm

h=21cm

i) area of base or area of each end = pie X r2

            22/7 X14X14=22x2x14=616 cm2

ii) curved surface area= pie X r X h

                                          = 22/7 X 14 X 21=22X2X21 =921 cm

iii) total surface area = 2(base area) + curved surface area

                                           = 2(616)+921=1232+921=2153 cm2
