diameter d = 14 cm
radius r = d/2
r = 7 cm
h = 40 cm
csa = 2πrh
= 2*22/7*7*40
= 2*22*40
=1760 cm2
tsa = 2πrh + 2πr2
= 2*22/7*7*40 + 2*22/7*(7)2
= 2*22*40 + 2*22*7
= 1760 + 408
= 2168 cm2
radius r = d/2
r = 7 cm
h = 40 cm
csa = 2πrh
= 2*22/7*7*40
= 2*22*40
=1760 cm2
tsa = 2πrh + 2πr2
= 2*22/7*7*40 + 2*22/7*(7)2
= 2*22*40 + 2*22*7
= 1760 + 408
= 2168 cm2
