Curved surface area of hemisphere of radius 12cm is

The csa of hemisphere refers to the area of the curved surface that forms the exterior of a hemisphere. A hemisphere is essentially half of a sphere, which means it is formed by cutting a sphere into two equal halves. In this case, we are given that the radius of the hemisphere is 12 cm.

To calculate the csa of hemisphere, we use the formula:

Curved Surface Area of Hemisphere = 2πr²

Where:

• π is a constant approximately equal to 3.1416
• r is the radius of the hemisphere

Now, substituting the value of r = 12 cm into the formula, we get:

csa of hemisphere = 2π(12)²

This simplifies to:

csa of hemisphere = 2π × 144 = 288π cm²

Therefore, the curved surface area of the hemisphere with a radius of 12 cm is equal to 288π cm².
