Surface Area of Pyramids and Cones Flashcards
What is the formula for the Lateral Area of a Regular Square Pyramid?
LA=1/2Pl. l=Slant Height and P=Perimeter.
What is the formula for the Surface Area of a Regular Square Pyramid?
SA=L+B, or S=1/2Pl+B. B=Base and l=Slant Height and P=Perimeter.
What is the Vertex of a Cone?
The point opposite the base.
What is the Axis of a Cone?
The segment with endpoints at the vertex and the center of the base.
Where is the Axis of a Right Cone?
It is Perpendicular to the Base.
What is the Slant Height of a Right Cone?
The distance from the Vertex of a Right Cone to a point on the edge of the Base.
What is the formula for the Lateral Area of a Right Cone?
LA=(pi)rl. l=Slant Height.
What is the formula for the Surface Area of a Right Cone?
SA=L+B, or S=(pi)rl+(pi)r^2. L=Lateral Area, l=Slant Height, and B=Base Area.
How do you find the Surface Area of Composite Three-Dimensional Figures?
You combine the Surface Areas of the smaller figures that make up the Composite Figure.
What is the Altitude of a Cone?
A perpendicular segment from the Vertex of the cone to the plane of the base.
