Luas Selimut = (keliling alas) x (tinggi)
= (2 . π . 35) x (14)
= (2 . 22/7 . 35) x (14)
= 220 x 14
= 880 cm²
b.)
Luas permukaan tabung = Luas alas x 2 + luas selimut
= (π . r²) x 2 + 880
= (22/7 . 35²) x 2 + 880
= 3850 x 2 + 880
= 7700 + 880
= 8580 cm²
c.)
Volume = Luas alas x tinggi
= 3850 x 880 cm³
= 3.388.000
