The surface area of a sphere of radius r is 4 π r^2. Half of this is 2 π r^2. If this is what is meant by the surface area of a hemisphere then 2 π r^2 = 1062.

In hemisphere,
Total surface area(TSA)= 3πr²
Curved surface area(CSA)= 2πr²
Volume = (2/3)πr³
Here,
r is radius
use π= 22/7 or 3.14 (according to convenience)

Total Area of a Hemisphere Surface

Understanding the concept of the total area of a hemisphere surface involves knowing the formula for calculating it. A hemisphere is half of a sphere and has a curved surface along with a flat circular base.

Formula for Total Area of a Hemisphere Surface

The formula for the total area of a hemisphere surface is given by:
\[ A = 3 \times \pi \times r^2 \]

where:
- A is the total surface area of the hemisphere
- r is the radius of the hemisphere
- π (pi) is a constant approximately equal to 3.14159

Calculating the Total Area

1. Measure the Radius: Start by measuring the radius of the hemisphere. The radius is the distance from the center of the hemisphere to any point on its curved surface.

2. Square the Radius: Square the radius value obtained in the previous step. This is done by multiplying the radius by itself.

3. Multiply by 3π: Multiply the squared radius by 3 and then by π. This will give you the total area of the hemisphere surface.

4. Units: Remember to include the appropriate units when expressing the total area. The units will be squared since area is measured in square units.

By following these steps and using the formula provided, you can accurately calculate the total area of a hemisphere surface. This knowledge is essential for various fields such as mathematics, engineering, and physics.
