FAQs on Formulas for Hemisphere Video Lecture - Mathematics (Maths) Class 10

1. What is a hemisphere and how is it defined?
Ans. A hemisphere is a three-dimensional geometric shape that is formed by dividing a sphere into two equal parts. It is defined as half of a sphere.
2. How can we calculate the surface area of a hemisphere?
Ans. The surface area of a hemisphere can be calculated using the formula 2πr^2, where r is the radius of the hemisphere.
3. What is the volume of a hemisphere and how can it be calculated?
Ans. The volume of a hemisphere can be calculated using the formula (2/3)πr^3, where r is the radius of the hemisphere.
4. How can we find the curved surface area of a hemisphere?
Ans. The curved surface area of a hemisphere can be found using the formula 2πr^2, where r is the radius of the hemisphere. However, since the curved surface of a hemisphere is a half-circle, the formula can also be written as πr^2.
5. Can we find the diameter of a hemisphere if the radius is given?
Ans. Yes, the diameter of a hemisphere can be found by multiplying the radius by 2. So, if the radius is given, the diameter can be obtained by simply doubling the radius value.
