A circular paddle wheel of radius 2 ft is lowered into a flowing river. The current causes the wheel to rotate at a speed of 15 rpm. (a) What is the angular speed? Round to one decimal place. The angular speed is approximately rad/min.

Step 1
First, we need to find the volume of the paddle wheel. The volume of a cylinder (which the paddle wheel resembles) is given by the formula V = πr^2h, where r is the radius and h is the height. Plugging in the values, we get V = π(14 cm)^2(15 cm) = 2940π cm^3. Show more…
