Find the volume of a cube with the base edge of 13cm.

You decide instead to take the train there. the train will take 135 minutes. convert this into hours and minutes.

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

Solve the formula ax+ by = c for x.
