You are able to multiply both the numerator and the deliminator to get the bigger fraction
Answer:
.
Step-by-step explanation:
I graphed the region in the image below. The blue line is y=3, the purple line is x=1 and the green curve is y = 
. The shaded region in blue is the region we are going to rotate.
Now, to find the volume v= 
where a=1, b=3 (left and right points of the region), p(x) is the distance from the rotation axis to the diferential Δx, we say p(x)=x and h(x) is the height of the region, in this case is h(x)= 
. Then,
v = 
= 
= 
= 
= 
= .

<span>When used in reference to a square, the radius is the distance from the center of the square to any of the four vertices, or where two sides intersect. Because a square has four right angles, you can find the diameter of the square using the Pythagorean Theorem. Multiply the side length of the square by itself.
