I think you meant "wide." :) Since it is a pipe, you should know that it is the shape of a cylinder. Therefore, the formula would be: πr^2h. Substitute the height for h. (π(4.5)^2(13). Since it's 9 cm wide total, divide it by 2 to get the radius (part of formula), which is 4.5 So multiply π times 4.5^2 (which equals 20.25) times 13. This all will equal 826.605. You can simplify this decimal to 827. Therefore, the volume is 827 cm^3.
Based on the above, the interval will their systolic pressure be lowest is 4pm to 5pm.
<h3>What is the interval about?</h3>
From the function given above, the lowest systolic pression can be seen from 5 and 8 hours after taken the medication.
Therefore, this will fall into or between the interval of 2pm to 5pm.
And as such, looking at the question, the option that best fit into this time range is 4pm to 5pm.
Therefore, Based on the above, the interval will their systolic pressure be lowest is 4pm to 5pm.
