# NCERT Solutions for Class 9 Maths Chapter 13 Surface Areas and Volumes: Download Free PDF Class 9 Maths Chapter 13 NCERT Solutions: The chapter talks about the surface areas and volumes of cylinders, cuboid and cubes, also the cones and spheres. The cuboids have been broken down to layouts so that each side of the cuboids explains the area and surface parameters. Further, formulas are given to solve problems related to cuboids, cylinders and spheres. Here the length of the sheet is equal to the base's circumference, which is circular and equal to 2πr. The top part and bottom portion of the cylinder are circular and have the area 2πr2.

• The chapter talks about the other shapes which are curved and have their own areas and mass.
• Measurement of the cuboids, spheres and cylindrical shape has been done. The inner, outer and the top surface of the cylinder is determined using certain formulas and theorems.
• A circle is a quadrilateral with infinite sides. It is a closed plane figure whose point lies at a constant distance known as "Radius" from a fixed point which is known as the centre.
• The sphere is a three-dimensional solid figure which can be considered a 3D figure for a circle.
• Every point on the sphere lies at a constant distance called the radius from the centre of the circle.
• Hemisphere is said to be formed when the sphere is cut into half. It also talks about volume of a hemisphere.
• The capacity of the sphere or cuboid is called the volume.
• The formula to measure the volume of the cubic unit is edge × edge × edge = a3
• Problems related to the cylinder's measurement are calculated as "r" is the base radius, and "h" is the height of the cylinder.
