Jari jari =14cm Tinggi tabung=20cm a.V= b.luas selimut= c.luas lingkaran=

V = 22/7 x 14² x 20
= 22/7 x 28 x 20 = 22 x 4 x 20
= 44 x 20 = 880 cm³
Luas selimut = 2 x πr x t = 2 x 22/7 x 14 x 20 = 2 x 22 x 2 x 20 = 44 x 40 = 1.760 cm²
Luas lingkaran = πr² = 22/7 x 28 = 22 x 4 = 88 cm²

Semoga jawabannya benar^_^
