Total is 1120
interest is 3.5
interest earn in 1 yr be p
so is p/ 100 × 3.5 ×4 = 1120
1120÷4= p/100x 3.5
280=p/100 x 3.5
280÷3.5= p/100
80=p/100
p= 8000
The answer to the questions of volumes are given as follows
a) 
b) 
c)
d)
Generally, the questions are mathematically solved below
a) x-axis
if $y=4, x=16, x=0$
Using disk method
b) line y=4
if x=0, y=0 ;
Using shell method
![v=2 \pi\left[\frac{4 y^{3}}{3}-\frac{y^{4}}{4}\right]_{0}^{4} \\](https://tex.z-dn.net/?f=v%3D2%20%5Cpi%5Cleft%5B%5Cfrac%7B4%20y%5E%7B3%7D%7D%7B3%7D-%5Cfrac%7By%5E%7B4%7D%7D%7B4%7D%5Cright%5D_%7B0%7D%5E%7B4%7D%20%5C%5C)
![v=\frac{2 \pi}{12}[1024-768] \\](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B2%20%5Cpi%7D%7B12%7D%5B1024-768%5D%20%5C%5C)
c) y-axis
0 ≤ y ≤ 4
x=y^2
Using disk method
volume
d) line x=-1
y=√x, y=4, x=0
0 ≤ x ≤ 6
Using shell method
volume is
![V=2 \pi\left[\frac{x^{3 / 2}}{3 / 2}+\frac{x^{5 / 2}}{5 / 2}\right]_{0}^{16} \\](https://tex.z-dn.net/?f=V%3D2%20%5Cpi%5Cleft%5B%5Cfrac%7Bx%5E%7B3%20%2F%202%7D%7D%7B3%20%2F%202%7D%2B%5Cfrac%7Bx%5E%7B5%20%2F%202%7D%7D%7B5%20%2F%202%7D%5Cright%5D_%7B0%7D%5E%7B16%7D%20%5C%5C)

Answer:
Use the equation found in step 3 and the remaining information given in the problem to answer the question asked. In this case, you need to find x when y = 44 and z = 6. Example 2 – If f varies directly as g and inversely as the square of h, and f = 20 when g = 50 and h = 5, find f when g = 18 and h = 6.
