A cylinderical pipe is 28m long. its internal radius is 3.5cm and external radius is 5cm. calculate the volume in cm cube of the metal used in making the pipe and the volume of water in litres the pipe can hold when full. correct to 1d. p​

its 4 because 2 times 2 is 4, if you double the number two you get four

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
