About how accurately must the interior diameter of a 10-m high cylindrical storage tank be measured to calculate the tank's volume within 1% of its true value? . about how accurately must the tank's exterior diamter be measured to calculate the amount of paint it will take to paint the side of the tank to within 5% of the true amount?

The correct answers are half percentage and 2.5 percentage.

Explanation:

The volume of the cylinder is as follows;

                                    ....... (1)

Here, r is the radius and h is the height.

On differentiating on the both side.

                                 ........ (2)

Divide (2) by (1).

Put

To get the volume within 1% measure the radius (or the diameter) must be within half percentage of the true radius (or the diameter).

Put

To get the volume within 2.5% measure the radius (or the diameter) must be within half percentage of the true radius (or the diameter).

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
