correct 5a if needed answer b (both parts)

5. In Part of this lab, you will measure the mass, height and diameter of four cylinders composed of some unknown material a. Calculate the volume (in cm') of a cylinder with a measured height of 11.76 cm and a diameter of 7.22 cm. Show your work clearly h= 11.76 cm volume of cylinder 227 x (3.6) 2 x 7.22 cm 3 radius- 7.22/2 3.61 cm 295.717cm3 b. Each pair of mass and volume values (for each cylinder) will be plotted on a scatter plot, with mass on the y- axis and volume on the x-axis. A best-fit line will then be applied to the plotted data, How will you calculate the value of the slope of this best-fit line? How will the value of the slope help you identify the unknown material that the cylinders are made of
