FAQs on Mensuration Video Lecture - Mathematical Olympiad Class 8

1. What is mensuration in mathematics?
Ans. Mensuration in mathematics involves the study of the measurement of geometric figures like squares, rectangles, circles, etc., and calculating their area, perimeter, volume, and surface area.
2. How can we calculate the area of a rectangle?
Ans. The area of a rectangle can be calculated by multiplying its length and width. The formula for the area of a rectangle is A = length x width.
3. What is the formula for calculating the circumference of a circle?
Ans. The formula for calculating the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle.
4. How do we find the volume of a cube?
Ans. The volume of a cube can be found by cubing the length of its side. The formula for the volume of a cube is V = side x side x side.
5. How can we calculate the surface area of a cylinder?
Ans. The surface area of a cylinder can be calculated by adding the areas of its two circular bases and the lateral surface area. The formula for the surface area of a cylinder is SA = 2πr^2 + 2πrh, where r is the radius of the base and h is the height of the cylinder.
