Circle related rates problem
WebI am trying to solve a problem two ways and keep getting two different answers. The volume of a cone of radius r and height h is given by V = 1/3 pi r^2 h. If the radius and the height both increase at a constant rate of 1/2 cm per second, at what rate in cubic cm per sec, is the volume increasing when the height is 9 cm and the radius is 6 cm. WebNov 21, 2024 · Solution The circumference and radius of a circle are related by C = 2 π r. We are given information about how the length of r changes with respect to time; that is, we are told d r d t = 5 in/hr. We want to know how the length of C changes with respect to time, i.e., we want to know d C d t.
