CILINDRO π΄π = ππ2 π = βπ΄π
π
Ab = area di base Al = area laterale At = area totale V = volume C =circonferenza r=raggio di base h=altezza del cilindro
π = 3.14
π΄π = πΆ β β = 2ππβ
β = π΄π 2ππ
π = π΄π 2πβ
π΄π‘ = π΄π + 2π΄π
π΄π = π΄π‘ β 2 π΄π
π΄π = π΄π‘ β π΄π 2
π = π΄π β β = ππ2β
β = π ππ2
π = βπ πβ
Cilindro equilatero : β = 2π
