Answer:
the one for the finding the height is 3.3, the one with 7 as the height is 351.86, and the one with 3 as the height is 150.8
Step-by-step explanation:
h=V
πr2=41.5
π·22≈3.30247
V=πr2h=π·42·7≈351.85838
V=πr2h=π·42·3≈150.79645
Answer:
The angle <SXN measures 108 degrees, and the angle <SXV measures 72 degrees.
Step-by-step explanation:
To determined the angles <SXN and <SXV, you need to first figure out what <SNX amounts to and then use the angle-sum property of the triangle NSX.
The following is true:
<SNX = 90 - <QNX (this is because <QNS is a right angle)
and
<QNX = <YNP = 56 (given)
so
<SNX = 90 - 56 = 34 degrees
Now, using the triangle-sum property:
<SXN = 180 - <SNX - <XSN = 180 - 34 - 38 = 108 degrees
Now that you have <SXN, to determine <SXV use the property that <SXV is supplementary angle to <SXN, hence
<SXV = 180 - <SXN = 180 - 108 = 72 degrees
All done!

Answer:
The area of the searched region is 
Step-by-step explanation:
If you want to find the area of a region bounded by functions f(x) and G(x) between two limits (a,b), you have to do a double integral. you must first know which of the functions is greater than the other for the entire domain.
In this case, for 0<x<1, f(x)<g(x)
while for 1<x, g(x)<f(x).
Therefore if our domain is all real numbers superior to 0 (where the limit 0<a<1 and 1<b), we have to do 2 integrals:
A=A(a<x<1)+A(1<x<b)
Answer: b = −2
