=π*r* sqrt( r2+h^2). (sqrt= raiz cuadrada)
=π*r*(generatriz).
para este caso...
Al=π*5*13=65π cm2
Área total = Area lateral + Area de base (circulo...= πr^2)
At= 65π + π*5^2
At=90π cm2
Volumen= (1/3)*π*r^2*h
(1/3)π*(5^2)*sqrt( g^2 - r^2)
(1/3)π(25)*sqrt( 13^2 - 5^2)
(1/3)π(25)*12
(1/3)π(300)
100π cm3
