Last Wednesday, two friends met up after school to read the book they were both assigned in Literature class. Samir can read 3 pages per minute, and he had already read 70 pages. Jen, who has a reading speed of 4 pages per minute, had read 13 pages. Eventually they had read the same number of pages. How long did that take? How many pages had each of them read?

Drag and drop the answers into the boxes to complete this informal argument explaining how to derive the formula for the volume of a cone. since the volume of a cone is part of the volume of a cylinder with the same base and height, find the volume of a cylinder first. the base of a cylinder is a circle. the area of the base of a cylinder is , where r represents the radius. the volume of a cylinder can be described as slices of the base stacked upon each other. so, the volume of the cylinder can be found by multiplying the area of the circle by the height h of the cylinder. the volume of a cone is of the volume of a cylinder. therefore, the formula for the volume of a cone is 1/3 1/2 1/3πr^2h 1/2πr^2h πr^2h πr^2
