an introduction for the art integrated project on the topic comparison between right angled cone and cylinder
Answers
Answer:
A right circular cone is one whose axis is perpendicular to the plane of the base. We can generate a right cone by revolving a right triangle about one of its legs.In the figure, you can see a right circular cone, which has a circular base of radius r and whose axis is perpendicular to the base. The line which connects the vertex of the cone to the centre of the base is the height of the cone. The length at the outer edge of the cone, which connects a vertex to the end of the circular base is the slant height.
Curved surface area of right circular cone = π r l
Total surface area of a right circular cone = π(r + l) r
Volume of a right circular cone = 1/3π r2 h
a cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis. The perpendicular distance between the bases is the height, “h” and the distance from the axis to the outer surface is the radius “r” of the cylinder.
Below is the figure of the cylinder showing area and height.
has three major quantities, based on which we have the formulas.
Lateral Surface Area or curved surface area = 2πrh square units
Total Surface Area = 2πr(r+h) square units
Volume = V = πr2h cubic units
