toloong beserta caranya volume dan luas permukaan tabung tsb...

V=π×r×r×t
=22/7×21×21×24
=33.264
L=2πr(r+t)
2×22/7×21×(21+24)
132×45
5940

r= 21cm
t= 24cm

volume tabung = 22/7 x r^2 x t
= 22/7 x 21 x 21 x 24
= 66 x 21 x 24
= 33.264cm3

luas permukaan = 2 x 22/7 x r (r+t)
= 2 x 22/7 x 21 (21+24)
= 2 x 66 (45)
= 132 (45)
= 5940cm2

semoga membantu
