Area = C(pi)r + (pi)r2 Where: C = the side length of the cone r = radius of the base (pi)r2 = the base of the cone C(pi)r = outside of cone
Surface Area = 2(pi r 2) + (2 pi r)* h
2 times pi times the radius squared plus 2 times pi times the radius times the height equals surface area of a cylinder :]
r2 times pi plus d
h2πr^2Where h is the height of the cylinder, and r is the radius of one base.
