Question 1105128: A graduated cylinder, pictured, is used to measure solutions in a laboratory. It is open at the top and closed at the bottom.
On the picture 80ml cylinder
If a graduated cylinder has a height (h) that is 4 cm more than its radius (r) and a surface area of 16p cm2, use the equations below to calculate the diameter of the graduated cylinder. Give exact answer in fraction form.
Area of the side of a cylinder = 2πrh
