hitung luas permukaan bola jika volume bola 288 phi cm3

V = 4/3 x Π x r^3
288Π = 4/3 x Π x r^3
r^3 = 288/4/3
r^3 = 216
r = 3√216
r = 6 cm

Luas permukaan bola =
= 4 x Π x r^2
= 4 x 3,14 x 6 x 6
= 452,16 cm2

Semiga membantu

Dik: V = 288phi
Dit: luas permukaan?
-> V = 4/3 × phi × r^3
288phi = 4/3 × phi × r^3
288 = 4/3 × r^3
216 = r^3
6 = r
-> Lp = phi × r^2
= 3,14 × 6^2
= 3,14 × 36
= 113,04

Maaf kalau salah. Semoga membantu
