Penjelasan dengan langkah-langkah:
r = 49
t = 60
V = πr²t/3
V = 22/7 x 49² x 60/3
V = 22 x 49/7 x 49 x 20
V = 22 x 7 x 980
V = 154 x (1.000 - 20)
V = 154.000 - 3.080
V = 150.920 cm³
s = √(r² + t²)
s = √(49² + 60²)
s = √(2.401 + 3.600)
s = √6.001 cm
Lp = πr ( r + s)
Lp = 22/7 x 49 x (49 + √6001
Lp = 154(49 + √6001) cm²
