What is the formula of TSA of a hemisphere?

3πr2 square units
The total surface area of a hemisphere = 3πr2 square units “r” is the radius of the hemisphere.

What is TSA and TSA of hemisphere?

The total surface area of a hemisphere = flat surface area + curved surface area. We know that, the curved surface area of a hemisphere =2πr2 and flat surface area =πr2. ∴ Total surface area of a hemisphere =2πr2+πr2=3πr2.

What is the difference between TSA and CSA of hemisphere?

What is the Difference Between Total Surface Area of and Curved Surface Area of Hemisphere? Curved surface area of hemisphere is the area covered by the curved surface of a hemisphere, whereas total surface area is space covered by the curved surface and the base surface of the hemisphere in 2-D plane.

What is the ratio of TSA of solid hemisphere?

Hence, the required ratio is 3π:1.

What is CSA and TSA?

Curved Surface Area (CSA) – It includes the area of all the curved surfaces. Lateral Surface Area (LSA) – It includes the area of all the surface excluding the top and bottom areas. Total Surface Area (TSA) – It includes the area of all the surfaces of the object including the bases.

What is LSA of hemisphere?

LATERAL SURFACE AREA OF A HEMISPHERE IS 2PIEr^2.

What is TSA of cube?

TSA of cube = a2 + a2 + a2 + a2 + a2 +a2. TSA of cube = 6a2. A cube consists of ‘n’ number of square units. Hence the space covered by these square units on the surface of the cube is the surface area. Basically, the surface area is the sum of all the area of all the shapes that cover the surface of the shape or object …

What is TSA of cylinder?

The total surface area of a cylinder is equal to the sum of the areas of all its faces. The total surface area with radius ‘r’, and height ‘h’ is equal to the sum of the curved area and circular areas of the cylinder. TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units.

What is TSA CSA and LSA?

TSA or total surface area is the sum of areas of all the surfaces of an object. LSA or lateral surface area is the areas of the lateral surfaces of an object. CSA or curved surface area is the area of the curved surfaces of an object. CSA of cylinder or hemisphere are the same as their LSA.
