tolong jawab pakai cara yaa

1. diameter = 2 x r = 2 x 14 = 28
    luas alas = phi x r x r = 22/7 x 14 x 14 = 616
    volume = phi x r x r x t = 22/7 x 14 x 14 x 30 = 18480
2. diameter = 2 x r = 2 x 18 = 36
    luas alas = phi x r x r = 3,14 x 18 x 18 = 1017,36
    volume = phi x r x r x t = 3,14 x 18 x 18 x 40 = 40694,4
3. jari jari = diameter/2 = 70/2 = 35
    luas alas = phi x r x r = 22/7 x 35 x 35 = 3850
    volume = phi x r x r x t = 22/7 x 35 x 35 x 65 = 250250
4. diameter = 2 x r = 2 x 70 = 140
    luas alas = phi x r x r = 22/7 x 70 x 70 = 15400
    volume = phi x r x r x t = 22/7 x 70 x 70 x 100 = 1540000
5. jari jari = diameter/2 = 200/2 = 100
    luas alas = phi x r x r = 3,14 x 100 x 100 = 31400
    volume = phi x r x r x t = 3,14 x 100 x 100 x 140 = 4396000
