Berapa hasil dari 1. Jari2= 35 cm Tinggi= 50 V= 2 diameter= 21cm Tinggi = 30 cm Volume = 3 volume= 9240cm Tinggi=15cm Jari2= 4 volume =6930 cm Tinggi = 20 cm Ja

1 )
π . r² . t = v
22/7 . 35² . 50 =
22/7 . 1225 . 50 = 192500
2)
π . r² . t = v
22/7 . 10,5² . 30 =
22/7 . 110,25 . 30 = 10,395
3)
π . r² . t = v
22/7 . r² . 15 = 9240
330/7 . r² = 9240
r² = 9240 . 7/330
r² = 196
r = √196
= 14
4)
π . r² . t = v
22/7 . r² . 20 = 6930
440/7 . r² = 6930
r² = 6930 . 7/440
r² = 110,25
r = √ 110,25
