Circumference of cone
WebProcedure. Draw and cut a circle from a coloured chart paper of radius equal to the given slant height say ‘l’ of the cone. Mark a sector OAB such that major AB = circumference of the base of cone. i.e, if rbe the radius of cone then length of major arc AB =2πr. Cut the sector AOB. Fold the remaining paper by bringing the two radii OA and ... WebThe distance from the vertex of the cone to the base is the height of the cone. The circular base has measured value of radius. And the length of the cone from apex to any point on the circumference of the base is the …
