Volcabulary
__Cone__- a three-dimensional figure that consists of a circular base and a curved lateral surface that connects the base to a single point not in the plane of the base, called the vertex __Base__- circular bottom of the cone __Lateral surface__- connects the base to a single point not in the plane of the base called the vertex __Altitude__- Is the perpendicular segment from the vertex to the plane of the base __Height__- length of altitude __Right Cone__- altitude of a cone that intersects the base of the cone at its center __Oblique cone__- it is not the altitude of a cone that intersects the base of the cone at its center __Slant height of a cone__- Line going down the cone

Surface Area of a Cone
S=L+B or S=pierl+pier^2

Surface Area of the Cone
The slant height of the cone is 10 and the radius is 5. Find the surface area of this cone?

L=pie(r)(s) L=pie(5)(10)=50pie

B=pie(r)^2 B=pie(5)^2=25pie

The surface area is S=L+B S=50pie+25pie= 75pie
