[ pi * r (r + 2t) ] + [ 2 * pi * r * s ] [ pi * 6 (6 + 16) ] + [ 2 * pi * 6 * 10 ] [ pi * 132] + [ pi * 120] pi * [132 + 120] pi * 252 = 252 pi cm kuadrat
smoga membantu, klu ga ada jawaban berarti salah soal

Ls kerucut = πrs
= π × 6 × 10
= 60π cm²
Ls tabung = 2πrt
= 2 × π × 6 × 8
= 96π cm²
L alas = πr²
= π × 6²
= 36π cm²
L total = 192π cm² (A)
[ pi * 6 (6 + 16) ] + [ 2 * pi * 6 * 10 ]
[ pi * 132] + [ pi * 120]
pi * [132 + 120]
pi * 252 = 252 pi cm kuadrat
