Question

Hitunglah panjang jarijari bola dengan volume 38808 cm^3

(phi = 22/7)

Answer 1

V.bola= 4/3 x phi x r^3
38.808= 4/3 x 22/7 x r^3
38.808= 88/21r^3
    r^3 = 9.261
      r  = 21 cm

maaf kalo jawabannya salah

Answer 2

Volume = 4/3 x π x r³
38.808 = 4/3 x 22/7 r³
r³ = 38.808 x 3/4 x 7/22
r³ = 814968/88
r³ = 9621
r  = ∛9621
r = 21
