luas selimut kerucut 204,1cm kuadrat jika jari jari 5 cm dan phi 3,14 tentukan volume kerucut tersebut pke caranya ya kk....bsok d kumpulin... mksh bnyak...

Ls = 204,1 cm²
R = 5 cm
V = ...

cari s :
Ls = πRs
204,1 = (3,14)(5)s
s = 204,1 : 15,7 = 13 cm

cari t :
t = √s² - R² = √13² - 5² = √169 - 25 = √144 = 12 cm

cari V :
V = (1/3)πR²t = (1/3)(3,14)(5²)(12) = 314 cm³
