tolong cari volume pada mainan tersebut pake cara ya nanti saya kasih bintang 5 :D
= (π x 7^2 x 15) + (π x 10,5^2 x 15) + (π x 14^2 x 15)
= (π x 49 x 15) + (π x 110,25 x 15) + (π x 196 x 15)
= (154 x 15) + (346,5 x 15) + (616 x 15)
= 2.310 + 5.197,5 + 9.240
= 16.747,5 cm^3
Jawaban:
DIAMETER 1 = 14 CM
Jari² 1 = 14/2 = 7 cm
DIAMETER 2 = 14+7 = 21 CM
jari² 2 =21/2 = 10,5 cm
DIAMETER 3 = 21 + 7 = 28 CM
jari² 3 = 28/2 = 14
TINGGI NYA = 45 / 3 = 15 CM
VOLUME 1 = π × r² 1 x t
= 22/7 × 7² × 15 = 2310 cm³
VOLUME 2 = π × r² 2 × t
= 3,14 × 10,5² × 15
= 5192,775 = 5193 cm³
VOLUME 3 = π × r² 3 × t
= 22/7 × 14² × 15 = 9240 cm³
MAKA
VOLUME 1 + VOLUME 2 + VOLUME 3
= 2310 + 5193 + 9240
= 16743 cm³
