Extracted text: Topics: Joint and Combined Variation nstruction: Find the equation of variation. Then solve for the missing value. 1. The volume of a cylindrical can varies jointly with its height and the square of its radius. Suppose that the radius is 3.5 cm, the height is 11.2 cm, and the volume is 430.8 cm3. Solve for the constant of variation and equation of variation. and z 4. %3D 2. y varies jointly as x and the square of z, and y = 4 when x = 50and z =. Find y when x = 3.y varies directly as x and inversely as z, and y = 4 when x = 3 and z = 6. Find y when x = 5 and z = 20.
