Answer:
Step-by-step explanation:
We are given that curves y=
is rotated about x=4 .
Given that y=0 and x=2
We have to find the volume V generated by rotating the region bounded by the curves with the help of method of cylindrical shells.
First we find the intersection point
Substitute y=0 then we get
0=
x=0
Hence, x changes from 0 to 2.
Radius =4-x
Height of cylinder =y=
Surface area of cylinder =
Volume V generated by the rotating curves
=
V=
V=![2\pi[\frac{12x^5}{5}-\frac{x^6}{2}]^2_0](https://tex.z-dn.net/?f=2%5Cpi%5B%5Cfrac%7B12x%5E5%7D%7B5%7D-%5Cfrac%7Bx%5E6%7D%7B2%7D%5D%5E2_0)
V=![2\pi[\frac{384}{5}-32]](https://tex.z-dn.net/?f=2%5Cpi%5B%5Cfrac%7B384%7D%7B5%7D-32%5D)
V=
Hence, the volume V generated by rotating the region by the given curves about x =4=
.
X=120
2/5-(x/300)=0
Simplify= X/300
2/5-X/300=0
Simplify=2/5
2/5-X/300=0
The left denominater is: 5
The right denominater is: 300
Answer:
B
Step-by-step explanation:
You would need to convert the fractions to a denominator of 15 because it's the closest denominator for both.
So 1 and 2/5 can be changed to 1 and 6/15
And 1 and 1/3 can be changed to 5/15
So what you do is multiply both the numerator and denominator by how much you need to multiply to get to 15 and the denominator.
You would then add the fractions, leaving the answer to be 2 and 11/15
So for example 2 * 3 = 6 and 5 * 3 = 15, meaning the fraction would be 6/15
