Perimeter of hollow circle

WebA sector of a circle is a part of a circle enclosed by two radii and an arc between them. We name the sectors based on the type of arc between the radii. If the central angle is less than 1 8 0 ∘ or 𝜋 rad, we refer to this as a minor sector. If the central angle is larger than that, we refer to this as a major sector. WebThe volume of a cylinder = Area of the base × Height of the cylinder = πr²h. Lateral Surface Area = Perimeter of base × height = 2πrh = πdh. Total Surface Area = Lateral Surface Area + Area of bases = 2πrh + 2πr² = 2πr (h+r) Another aspect of cylinders that we must learn is that of a hollow cylinder, like a pipe for example.
