R = 1/2 x 10 = 5 cm volum tabung volum = π x r² x t = 3,14 x 5 x 5 x 28 = 78,5 x 28 = 2198 cm³ volume krucut volum = 1/3 x π x r² xt = 1/3 x 3,14 x 5 x 5 x 18 = 78,5 x 6 = 471 cm² volum total volum = 2198+471 = 2669 cm³

Volume tabung= luas lingkaran=3,14X10 cm X10 cm= 314 cm 314X28 cm= 8792 cm kubik
Volume kerucut= luas lingkaran=3,14X10 cm X 10 cm=314 cm 1/3 X 314 cm2 X 18 cm= 1884 cm3
= 5 cm
volum tabung
volum = π x r² x t
= 3,14 x 5 x 5 x 28
= 78,5 x 28
= 2198 cm³
volume krucut
volum = 1/3 x π x r² xt
= 1/3 x 3,14 x 5 x 5 x 18
= 78,5 x 6
= 471 cm²
volum total
volum = 2198+471
= 2669 cm³
luas lingkaran=3,14X10 cm X10 cm= 314 cm
314X28 cm= 8792 cm kubik
