Verified answer
Bangun Ruang Sisi Lengkung.L = πrs
s = L / (πr)
= 204,1 cm² / (3,14 × 5 cm) = 13 cm
t = √(s² - r²)
= √[(13 cm)² - (5 cm)²] = 12 cm

Diket = kerucutd = 10
luas selimut = 204,1 cm²
π =3,14
Ditanya=tinggi...?
Jawab=
Luas selimut = πrs
204,1=3,14.5.s
204,1=15,7.s
s=204,1/15,7
s=13cm
Maka,t=√s²-r²
t=√13²-5²
t=√169-25
t=√144
t=12cm
Jadi tinggi kerucut tsb adalah 12cm.
