what is the difference between total surface area and curved surface area?
5008
Curved surface area or lateral surface area is the area of the curved surface on these. Total surface area is the sum of curved surface area and the flat surfaces like base of a cylinder, base of a cone or base circular disc of a hemisphere.

If a solid is composed of flat surfaces, such as the cube on the right, the surface area is simply the sum of the areas of the flat surfaces (called faces). So, for example, if a each edge of a cube has a length s, the area of one face is s2 since it is a square.

There are two ends so their combinded surface area is 2 π * r2. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side.

From the surface area of a sphere, we can easily calculate the surface area of the hemisphere. The curved surface area of a hemisphere = 2πr2 square units. Where π is a constant whose value is equal to 3.14 approximately. “r” is the radius of the hemisphere.

The ratio is the surface area divided by the volume. This indicates how much surface area is available compared to how big the cell is. If the surface area to volume ratio is small, the cell is very big. If the ratio is big, the surface area is greater than the volume, and the cell is small.

Circles have area. Spheres have volume. The area of a circle with a radius of r is π * r^2, and the volume of a sphere with a radius of r is (4/3) * π * r^3.

The curved surface area of a sphere is 4(pi)r^2 or (pi)d^2.

The total surface area of a cone is the sum of the area of its base and the lateral (side) surface. ... A=πrl , where l is the slant height of the cone . Example 1: Find the lateral surface area of a right cone if the radius is 4 cm and the slant height is 5 cm.

In geometry, area is the 2-dimensional space or region occupied by a closed figure, while perimeter is the distance around a closed figure i.e. the length of the boundary. ... Two shapes may have the same perimeter, but different areas or may have the same area, but different perimeters.

The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid we take the sum of the area for each geometric form within the solid. The volume is a measure of how much a figure can hold and is measured in cubic units.

Surface Areas and Volume. Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area covered or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.

Surface Areas and Volumes. Curved surface area of a hemisphere with radius 7 cm is: 308 cm.

Lateral surface area refers to the area of a solid excluding the base. Total surface area refers to the net area which includes the base. and TSA = 2pi*r*h + 2pi*r*r. ... In a cylinder, when will we take the lateral surface area or the total surface area?

The area is the measurement of the size of flat-surface in a plane (two-dimensional) whereas surface area is the measurement of the exposed surface of a solid shape (three-dimensional). This is the key difference between area and surface area.

Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h (h is the height of the cylinder, r is the radius of the top) Surface Area = Areas of top and bottom +Area of the side. Surface Area = 2(Area of top) + (perimeter of top)* height. Surface Area = 2(pi r 2) + (2 pi r)* h. In words, the easiest way is to think of a can.

Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side.

Take half the diameter, square it, multiply it by pi (3.1416) - that is the area of the end. Take the diameter, multiply it by pi, multiply it by the cylinder length - that is the area of the curved surface. Add the two areas together and you have the total surface area of the cylinder with one end open.
