1/3 x 3,14 x 5² x t = 314
26,17x t = 314
t = 314/26,17 =12
s =√ t² + r²
s = √12² + 5²
s= √144 + 25=√169=13cm
V = 314 cm^3
Mencari tinggi lebih dulu,
V = 1/3 x π x r² x t
314 = 1/3 x 3,14 x (5)² x t
314 = 1/3 x 3,14 x 25 x t
314 = 26,17 t
t = 314/26,17 = 12
Mencari garis pelukis,
s² = r²+t²
s² = 5² + 12²
s² = 25 + 144
s² = 169
s = √169
s = 13
Jadi garis pelukisnya adalah 13 cm
