Circle related rates problem
WebRelated Rates Problems 1.) If the radius r of a circle is increasing at the rateof 5 cm./min., at what is its a.) circumference changing when r = 2 cm. b.) area changing when r = 2 cm. 2.) The width x of a rectangle is increasing at therate of 5 in/mm. and length y is decreasing at the rate of 4 in./rnin. At what rate is its a.) perimeter ... WebWe can subtract 64 from both sides, we get 12. 12 times the derivative of h with respect to time is equal to negative 64. And then we just have to divide both sides by 12. And so now we get a little bit of a drum roll. The derivative, the rate of change of h with respect to time is equal to negative 64 divided by 12.
