Volume sebuah buah bola 288πcm^3 luas sisi kulit bola itu adalah
5dregensleyer
Volume bola = 288π 4/3 x π x r³ = 288π r³ = 288π/π x 3/4 r³ = 288 x 3/4 r³ = 216 r = ∛216 r = 6 luas sisi bola Lp = 4 x π x r² = 4 x π x 6 x 6 = 144π

Volume = 4/3 π r³ = 288π 4r³ = 288x3 r³ = 864/4 r³ = 216 r = ∛216 r = 6 cm
4/3 x π x r³ = 288π
r³ = 288π/π x 3/4
r³ = 288 x 3/4
r³ = 216
r = ∛216
r = 6
luas sisi bola
Lp = 4 x π x r²
= 4 x π x 6 x 6
= 144π
4r³ = 288x3
r³ = 864/4
r³ = 216
r = ∛216
r = 6 cm
Luas sisi = 4πr² = 4π.6² = 144π cm²
