Joy baked 2 pizzas and cut each pizza into 8 slices. Joy and her brother ate all but 4 slices of the pizza. Which equation can be used to find s, the number of slices joy and her brother ate? 2 x s = 8 x 4

2 x 8 + 4 = s

s = (2 + 8) - 4

8 x 2 = s + 4

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
