Question

5. A cylinder has a mass of 10.0 ± 0.1 g, a height of 5.00 ± 0.01 cm, and a radius of 4.00 ± 0.01 mm. Calculate the density, including uncertainty, in kg/m^3.

6. The sides of a right triangle are measured to be a = 7.80 ± 0.02 cm and b = 6.40 ± 0.02 cm. Determine the length of the hypotenuse of the triangle (given by ?^2 +?^2 = ?^2) and the uncertainty in the length. (Hint: you need to use the derivative equation to find the uncertainty.)

7. If you drive 146 miles in a time of 3.25 hours, what is your average speed in km/h and m/s? How long would it take to travel an additional 175 km at this average speed?
