How do you work out the surface area of a hemisphere?

Surface Area of Hemisphere Formula:

The surface area, S S , of a hemisphere is determined by the following formula S=3×r2×π S = 3 × r 2 × π where r r is the length of the radius of the hemisphere and π≈3.14 π ≈ 3.14 .

What is surface area of hemisphere?

Total surface area of a hemisphere: A = 3 * π * r² , Surface to volume ratio of a hemisphere: A / V = 9 / (2 * r) .

What is the formula for hemisphere?

Therefore, the volume of a hemisphere formula is as follows: V = V(sphere)/2 , V = 2/3 * π * r³ .

How do you find the surface area?

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

What is the total surface area of cylinder?

So, total surface area of cylinder = Area of curved surface + Area of two circular regions. = CSA of cylinder + πr2 + πr2. = 2πrh + 2πr2. Therefore, Total surface area of cylinder = 2πr (h + r) sq.

What is the difference between curved surface area and total surface area of hemisphere?

Curved Surface Area (CSA) only includes the area of all the curved parts of the hemisphere whereas Total Surface Area (TSA) includes the curved surface area as well as surface area formed on the top of the hemisphere.

Is surface area a TSA or CSA?

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 the total surface area of a hollow sphere?

The total surface area of a hollow sphere is equal to the CSA of hollow sphere as a hollow sphere has only one surface that constitutes it. Example-1: Calculate the volume and TSA of hollow sphere with outer and inner radii 5cm and 3cm respectively.

What is the curved surface area of cylinder?

The formula to calculate the total surface area of a cylinder is given as, the total surface area of cylinder = 2πr(h + r), while the curved surface area of cylinder formula is, curved/lateral surface area of cylinder = 2πrh, where 'r' is the radius of the base and 'h' is the height of the cylinder.

What is the volume of this cylinder?

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm.
