Plotas

Straipsnis iš Vikipedijos, laisvosios enciklopedijos.

Plotas - matas, nusakantis tam tikro erdvės regiono dydį. Objekto paviršiaus plotas lygus visų išorinių šonų plotų sumai. Tobulai uždaros dvimatės kreivės (t.y. apskritimo) plotas skaičiuojamas naudojant apskritimo ilgio integralą. Taigi, kadangi ilgis yra 2πr, plotas lygus πr².
