Answer:
The question has some missing details such as ; Use cylindrical shells to find the volume of the remaining solid if the remaining solid is 8cm high. I have however solved it using the value of 8cm, you can use the same approach to solve for the volume irrespective of the value of the height you are given.
Step-by-step explanation:
The detailed step by step analysis and appropriate Integration by susbtitution in order to get the volume of the remaining solid is as shown in the attached file.
Answer:
29
Step-by-step explanation:
(1.2 x 10-4) + (2.4 x 10-3)
Simplify
1.2 x 10- 4 = 8
2.4 x 10- 3 = 21
Add both sums to get 29!
SCIENTIFIC NOTATION
2.9 x 10 to the 1st power
Move the decimal over to make a number less than ten, so that makes 2.9 and 10 to the 1st because you moved the decimal once! Hope this is better

4.75 lbs of water and 0.25 lbs of sugar is needed to make 5% of syrup.
<u>Solution:</u>
Let us assume that x is the required pounds sugar to make 5% syrup

which is 
On solving we get,
![\Rightarrow\frac{x}{5} =0.05 [5\%=\frac{5}{100}]](https://tex.z-dn.net/?f=%5CRightarrow%5Cfrac%7Bx%7D%7B5%7D%20%3D0.05%20%5B5%5C%25%3D%5Cfrac%7B5%7D%7B100%7D%5D)

If the required sugar to make 5% syrup is 0.25 lbs then the remaining quantity in the total sugar syrup would be water. That is,

So, the required amount is 0.25 lbs of sugar and 4.75 lbs of water.
