Suppose you have a coffee mug with a cylindrical shape (the radius is uniform, in other words). What is its inside radius, in centimeters, if it holds 360 g of coffee when filled to a depth of 9.5 cm? Assume coffee has the same density as water, 1.00 g/cm3.

Answer 1

mass = volume x density
360g = volume x 1.00 g/cc
volume = 360 g/1.00 g/cc = 360 cc
volume of a cylinder = pi*r^2*h
v = 3.14 x r^2 * 9.5 cm
Solve for r
