tolong jawab pakai cara

d = 14 cm
r = 7 cm
t tabung = 12 cm
t kerucut = 36 cm - 12 cm = 24 cm

s = √r² + t²
   = √7² + 24²
   = √49 + 576
   = √625
   = 25 cm

Luas permukaan gabungan
= Luas selimut kerucut + Luas tabung tanpa tutup
= π x r x s + π x r ( r + 2t )
= 22/7 x 7 cm x 25 cm + 22/7 x 7 cm ( 7 cm + 2.12 cm )
= 22 cm x 25 cm + 22 cm x 31 cm
= 550 cm² + 682 cm²
= 1.232 cm²
