p - obwód koła = 2πl = 2 * 6 * π = 12π dm
1/2 p = 12π/2 = 6π dm
6π = 2πr
r - promień podstawy stożka = 6π/2π = 3 dm
Pp - pole podstawy stożka = πr² = 3²π = 9π dm²
h - wysokość stożka = √(l² - r²) = √(6² - 3²) = √(36 - 9) = √27 = 3√3 dm
V - objętość stożka = 1/3 * Pp * h = 1/3 * 9π dm² * 3√3 dm = 9π√3 dm³
