Volume of a Cone. The volume of a cone is equal to one-third the product of the area of the base and the height. It is given by the formula: where r is the radius of the base and h is the perpendicular height of the cone. Worksheet to calculate the volume of cones. Example: Calculate the volume of a cone if the height is 12 cm and the radius is 7 cm.
Describe the pine cone in terms of structure and function. The female pine cone is a compact structure formed from a central axis with whorls of sporophylls (scales) attached. The sporophylls are scale-like structures with two ovules at the base of each. The scales are open when the female cone is young in order to accept pollen delivered by the wind. After pollination the scales of the female cone close. The cone develops and enlarges over the next year or two as the pollen tube grows through the micropyle towards the archegonium. After fertilization the female cone becomes even larger and woody. When the seeds are completely developed the pine cone opens up to release the seeds.
