An hourglass sand timer drips 2 cm^3 of sand every minute. It has a radius of 4cm and a height of 15cm. When there is 7cm of sand in the hourglass, what rate is the depth of the sand decreasing (dv/dt) AND what is the rate that the radius is changing (dr/dt)? (This is a cone problem) HOW I NEED IT SET UP: EXAMPLE BUT WITH CYLINDER LENGTH AND RADIUS: v(t)= π ((r(t)^2)’ l(t) + r(t)^2 * l’(t)) product rule:...
