What else can I help you with?
Brenda went to attach a string of beads along the circular bottom edge of the lamp shade shown below The diameter of the bottom of the lamp shape is 16 centimeters?
To determine the length of the string needed, Brenda can calculate the circumference of the circular bottom edge using the formula: circumference = π * diameter. The circumference of the lamp shade is 16π cm, so Brenda will need a string of 16π cm in length to attach the beads along the circular bottom edge.
Does a cylinder have a curved and flat surface?
Yes, a cylinder has both curved and flat surface. Considering a solid cylinder standing on its end, the circular base and the circular top are flat surfaces. The surface connecting the top and bottom is curved.
Which solid figure has a flat surface that is a circle?
A solid figure that has a flat surface that is a circle is a cylinder. A cylinder consists of two circular bases connected by a curved surface. The flat circular surfaces are at the top and bottom of the cylinder. Another example is a sphere, which has a circular cross-section but is not flat overall.
How do you calculate area of column?
Surface Area = (Circumference)(Height)* Volume = ∏r2 x Height *If you want to include the top and the bottom in the surface area of the column you have to add the area of the top and bottom. So, the Total Surface Area = [(Circumference)(Height)] + 4(∏)(Radius2)
What is the base of a cylinder called?
The word "base" is just fine for this purpose.
A solid shape with curved surfaces and two congruent circular bases?
A cylinder because there are two circular bases on the bottom and top and in the middle is a curved surface. hope I helped
How do you find the surface area of a cone?
A cone has two surfaces, lateral surface and its circular surface at the base.The surface area of a cone is the sum of the areas of these two surfaces, i.e. (1) area of the lateral surface and (2) area of its base.Let us consider a right circular cone to find its surface area.The lateral surface area of a right circular cone is π r lwhere,r is the radius of the circle at the bottom of the cone, andl is the lateral height of the coneThe surface area of the bottom circle of a cone is the same as for any circle, π r2Thus the total surface area of a right circular cone is: π r l + πr2 OR π r (l + r)
What is the shape of the face on a cone?
The shape of the face on a cone is a circular base at the bottom and a curved surface that narrows smoothly to a point called the apex. This curved surface is referred to as the lateral face of the cone. Overall, a cone has one circular face (the base) and one curved surface.
How many surfaces on a solid hemisphere?
A solid hemisphere has two surfaces: one curved surface and one flat circular base. The curved surface forms the outer part of the hemisphere, while the flat base is the circular face at the bottom.
How many faces vertices and edges dose a cylender have?
A cylinder has 3 faces: two circular bases and one curved surface. It has 2 vertices located at the top and bottom circular edges, and it has an infinite number of edges along the curved surface where the circular bases meet. However, if considering just the circular edges, it has 2 edges.
What is the bottom of a cone called?
The bottom of a cone is called the base. It is a flat, circular surface that distinguishes the cone from other geometric shapes. The apex of the cone is the point opposite the base, where the sides converge.
What is the number of bases in a cone?
A cone has one base, which is a circular shape. The curved surface extends from the base to the apex (the tip of the cone). Therefore, while it has a circular base at the bottom, the entire structure is defined by this single base.
