Which explanation can be used to informally derive the formula for the volume of a cone? a cylinder is exactly 3 times bigger than a cone with the same height and radius. therefore, the formula for the volume of a cone is 13 of the volume of a cylinder with the same height and radius. a cone is similar to a triangular pyramid except that a cone has curved edges. therefore, the formula for the volume of a cone can be derived by using the formula of a triangular pyramid and using the radius instead of the base length. a cone is approximately the same size as 1.5 spheres. using the formula for the volume of a sphere and multiplying it by 1.5 will give the formula for the volume of a cone. a cone consists of a circle as a base and triangles for its body. the formula for the volume of a cone can be derived by adding the formula for the area of circle and the area of the number of triangles that will cover the body of a cone.

Which explanation can be used to informally derive the formula for the volume of a cylinder? a cylinder consists of 2 circles on the top and the bottom. determine the circumference of each circle and add the circumferences together. to get the body of the cylinder, multiply it by the height of the cylinder. a cylinder is similar to a triangular prism except it does not have edges. the volume of a cylinder can be found by using the volume of a triangular prism. however, instead of using the base length of the triangle, use the radius of the cylinder. a cylinder is approximately equivalent to 3.5 spheres of the same radius stacked on top of each other. the volume of a cylinder is the volume of a sphere times 3.5. a cylinder is like a stack of circles. the volume of a cylinder would be the area of the circle times the height of the cylinder. the height of the cylinder represents how many circles are in the stack.
