<span>Let
x = the 10s digit
y = the units
N1----------> original number
</span>N2----------> new number
<span>N2=N1+36--------- >N2-N1=36
y+x=8------------- > equation (I)
then
10x + y = N1
10y+x=N2
(10y+x)-(10x+y)=36- -----> 9y-9x=36------- > y-x=4----------- > equation (II)
resolving (I) and (II)
</span> y+x=8
y- x=4<span>
-----------------
2y+0x=12--------------- >y=6
then
x=8-y=8-6=2----------> x=2
N1=26 and N2=62
the two digit number is 26</span>

Answer: 
Step-by-step explanation:
Given
Curve is 
boundary is y=0 i.e.
The volume of solid generated when rotated about the x-axis is
Putting values we get
![\Rightarrow V=\int_{-1}^{1}\pi (3-3x^2)^2dx\\\\\Rightarrow V=\int_{-1}^{1}\pi(9+9x^4-18x^2)dx\\\\\Rightarrow V=\pi \left [ \frac{9x^5}{5} - 6 x^3 + 9 x\right ]_{-1}^{1}\\\\\Rightarrow V=9.6\pi](https://tex.z-dn.net/?f=%5CRightarrow%20V%3D%5Cint_%7B-1%7D%5E%7B1%7D%5Cpi%20%283-3x%5E2%29%5E2dx%5C%5C%5C%5C%5CRightarrow%20V%3D%5Cint_%7B-1%7D%5E%7B1%7D%5Cpi%289%2B9x%5E4-18x%5E2%29dx%5C%5C%5C%5C%5CRightarrow%20V%3D%5Cpi%20%5Cleft%20%5B%20%20%5Cfrac%7B9x%5E5%7D%7B5%7D%20-%206%20x%5E3%20%2B%209%20x%5Cright%20%5D_%7B-1%7D%5E%7B1%7D%5C%5C%5C%5C%5CRightarrow%20V%3D9.6%5Cpi)
Answer:
Step-by-step explanation:
11:1
11*2 : 1*2 = 22 : 2
11*3 : 1 *3 = 33 : 3
11*4 : 1 * 4 = 44 : 4
To find equivalent fractions multiply with the same number
