surface+area+of+a+cone.

Cone: A three- dimensional figure with a circular base and a lateral surface that has a curve in it that connects to a vertex which is a single point not located on the bases plane.

Altitude: perpendiclular segment from the vertex oto the plane

Hight: altidude lenght

S = L + B or S = πrh + πr^2

S is surface are L is lateral area B is base h is slant height r is radius

a construction cone is 1 foot across the base and the slant hight is 2 feet S = π.5*1 + π.5^2 S = ~2.36
