Your science class visits an aquarium. In a report on your class's visit, you sketch one of the fish tanks
and round the dimensions as shown in the diagram at the
right. You use the rounded dimensions to state that the
volume of the tank is approximately (7)(5)(3) = 105 m3.
What is the percent error in your volume calculation due
to rounding?

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
