1. ### Volume of cross sections using rectangles

Yes, it does sit on the area with rectangular cross sections perpendicular to the x and y plane and the bases of the rectangular cross section are perpendicular to the x axis. I just need to find the volume using the given information. Also i realize an error in my work : A=HB A=(1/2B)B =3/2√...
2. ### Volume of cross sections using isosceles right triangle

Its perpendicular to the x axis not the hypotenuse. Also I combined the variables as one because the height is equal to the base. Also, we weren't taught thickness so that information is not needed. However , in my problem i realize i forgot to plug in X^2 So redoing my work it would be ...
3. ### Volume of cross sections using isosceles right triangle

Homework Statement The area is bounded by the equation y=x^2, x axis and the line x=3 and is perpendicular to the x axis Homework Equations A=1/2bh Height=Base The Attempt at a Solution A=1/2B^2 V=1/2B^2 from 0 to 3 V=1/2 B^3/3 from 0 to 3 V=B^3/6 from 0 to 3 V=27/6 please...
4. ### Volume of cross sections using rectangles

Homework Statement The area bounded by y=√x, the x axis and the line x=9 and is perpendicular to the x axis. find the volume of the cross section using rectangle with the h=1/2b Homework Equations The Attempt at a Solution I just want to know if i'm correct or on the right track...
5. ### Volume of a square using cross section

I drew the picture and y=9 is the higher graph and y=x^2 is the lower graph. So from there do you do (9-x^2)^2 and take the integral from -3 to 3 ?
6. ### Volume of a square using cross section

Homework Statement What is the volume if the area bounded by y=x^2 and y=9 and the cross sections are perpendicular to the y axis Homework Equations The Attempt at a Solution I have no idea
