A. r = 7 cm t = 16 cm diameter = 2 r = 2. 7 = 14 cm luas alas = πr² = 22/7 x 7² = 154 cm² volume = luas alas x tinggi = 154 x 16 = 2464 cm³
b. t = 30 cm diameter = 50 cm jari - jari = d/2 = 50/2 = 25 cm luas alas = πr² = 3,14 x 25² = 1962,5 cm² volume = luas alas x tinggi = 1962,5 x 30 = 58.875 cm³
