= 2 . π . r . t
= 2 . π . 6 . 8
= 96πcm²
Luas lingkaran pd tabung
= π . r²
= π . 6²
= π . 36
= 36πcm²
untuk mencari sisimiring pd kerucut, gunakan phytagoras
s² = 8² + 6²
s² = 64 + 36
s² = 100
s = √100
s = 10cm
Luas selimut kerucut
= π . r . s
= π . 6 . 10
= π . 60
= 60πcm²
LP bangun tsb
= Lselimut tabung + Llingkaran tabung + Lselimut kerucut
= 96πcm² + 36πcm² + 60πcm²
= 192π cm²
Jadi Lp bngun tsb adalah 192π cm² ==>A
