Maria built a tool that checks the rate of flow of liquid from one container to another. The tool consists of a cylindrical container attached to a cubic container. The cylinder has a diameter of 5 cm and a height of 6 cm, the cube has a side length of 5 cm, as shown in the diagram.
what is the volume of the two containers of make up Maria’s tool?

A. 266.30 cm³
B. 596.00 cm³
C. 242.75 cm³
D. 690.20 cm³

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
