682 divide by 4 = 170.5
is that right no or yes
Answer: 1208.96
Step-by-step explanation:
The volume of the cylinder is ![(\pi)(4^2)(4)=64\pi](https://tex.z-dn.net/?f=%28%5Cpi%29%284%5E2%29%284%29%3D64%5Cpi)
The volume of the prism is ![(6)(12)(14)=1008](https://tex.z-dn.net/?f=%286%29%2812%29%2814%29%3D1008)
So, the total volume is ![1008+64\pi=\boxed{1208.96}](https://tex.z-dn.net/?f=1008%2B64%5Cpi%3D%5Cboxed%7B1208.96%7D)
Answer: 9.70%
Step-by-step explanation:
The formula to find the percentage error is given by :-
![\%\text{ error}=\dfrac{|\text{Estimate-Actual}|}{\text{Actual}}\times100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20error%7D%3D%5Cdfrac%7B%7C%5Ctext%7BEstimate-Actual%7D%7C%7D%7B%5Ctext%7BActual%7D%7D%5Ctimes100)
Given : Actual mass of zinc oxide used by pharmacist = 28.35 g
Estimated mass of zinc oxide used by pharmacist =31.1 g
Now, ![\%\text{ error}=\dfrac{|31.1-28.35|}{28.35}\times100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20error%7D%3D%5Cdfrac%7B%7C31.1-28.35%7C%7D%7B28.35%7D%5Ctimes100)
i.e. ![\%\text{ error}=\dfrac{2.75}{28.35}\times100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20error%7D%3D%5Cdfrac%7B2.75%7D%7B28.35%7D%5Ctimes100)
i.e. ![\%\text{ error}=9.70017636684\approx9.70\%](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20error%7D%3D9.70017636684%5Capprox9.70%5C%25)
Hence, the percentage of error on the basis of the desired quantity.= 9.70%
