A scanning electron micrograph of xylem vessels in a corn root shows the vessels magnified by a factor of 608. In the micrograph the xylem vessel is 5.60 cm in diameter. What is the diameter of the vessel itself, answer in cm? and By what factor has the cross-sectional area of the vessel been increased in the micrograph?

In the fall of 2002, scientists at Los Alamos National Laboratory determined that the critical mass of neptunium-237 is about 60 kg. The critical mass of a fissionable material is the minimum amount that must be brought together to start a nuclear chain reaction. Neptunium-237 has a density of 19.5 g/cm3. What would be the radius of a sphere of this material that has a critical mass?
The World Health Organization differentiates bone diseases using bone density measurements. The table given below is the criteria for diagnosing different bone diseases (assuming that the mean normal bone density is 1.8 g/cm and that 1SD is approximately 10% of the mean bone density). CATEGORY Osteoporosis Osteopenia (Low Bone Mass) 1.98 g/cm3 Normal Bone Density 1.98 Osteopetrosis What would be the diagnosis of a bone sample if its weight in air is 52 grams and its weight in water is 20 grams?
The volume of air in one beach ball is 36π in3. What is the volume of air in a ball whose radius is 3 inches greater than the first beach ball?
A spherical balloon is partially blown up and its surface area is measured. More air is then added, increasing the volume of the balloon. If the surface area of the balloon expands by a factor of 9.90 during this procedure, by what factor does the radius of the balloon increase?
Grains of fine California beach sand are approximately spheres with an average radius of 50 μm and are made of silicon dioxide, which has a density of 2.5 × 103 kg/m3. What mass of sand grains would have a total surface area (the total area of all the individual spheres) equal to the surface area of a cube 1.2 m on an edge?
A circular hole of radius 8.467 10-1 cm must be cut into the front panel of a display unit. The tolerance is 2.0 10-3 cm, which means the hole cannot differ by more than this quantity from the desired radius. If the actual hole is larger than the desired radius by the allowed tolerance, what is the difference between the actual area and the desired area of the hole?
A paint can has 0.776 U.S. gallons of paint. If this paint is used to coat a wall evenly (wall area = 15.3 m^2), how thick is the layer of wet paint? Give your answer in millimeters. Assume that the dry paint has the same volume as the wet paint.

A contractor is painting the ceilings. a Small squre bedroom is being painted, along with a large, rectangular common room. The short wall of the common room is the sams size as each of the bedroom walls. The other wall is 2 meters longer. If a contractor has enough paint to cover 80 square meters, and that is just enough for two coats of paint on both ceilings - what are the dimensions of the common room? The common room has a short wallt that is ___ meters long and a long wall that is ___ meters long.
