Learn the surface area of a hemisphere—curved and total—with stepwise formulas, clear examples, and smart tips for faster calculations. Perfect for board exams and quick revision. Here you will learn what is the formula for surface area of hemisphere (total and curved surface area of hemisphere ) with examples. Let’s begin – What is Hemisphere ? Let us take a solid sphere, and slice it exactly ‘through the middle’ with a plane that passes through its centre. It gets divided into two equal parts which is called a hemisphere . (Because ‘hemi’ means ‘half’) Formula for Surface Area of Hemisphere (i) Curved Surface Area of Hemisphere Curved Surface Area ( CSA ... Learn how to calculate the curved surface area ( CSA ) and the total surface area (TSA) of a hemisphere using formulas and examples. Find out the real-life applications of hemispheres and practice questions on area of hemisphere . The area of a hemisphere is the total space covered by its surface. There are two types of areas for a hemisphere : Curved Surface Area ( CSA ): This is the area of only the round curved part of the hemisphere , without including the flat base. The formula for this is: CSA = 2πr²
