Colleen and Jimmy have part-time jobs after school. Both have decided that they want to see how much money they can save
in one semester by placing part of their earnings each week into
a savings account. Colleen currently has $120 in her account and
plans to save $18 each week. Jimmy currently has $64 in his savings
account and plans to save $25 each week.

represents the total amount of money, in dollars, in each
of their savings accounts, y, in terms of the number of weeks,
x, that they place money in their respective accounts.

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
