x-axis. Notice that when each line segment is revolved around the axis, it produces a band. These bands are actually pieces of cones (think of an ice cream cone with the pointy end cut off). A piece of a cone like this is called a frustum of a cone. To find the surfac...
Homework Statement the curve y= sqrt(x² +1) , 0 ≤ x ≤ sqrt(2) is revolved about the x-axis to generate a surface. Find the area of the surface of...
Find the surface area of the solid in revolution generated by the area under y = x^2 + 12 on the x-axis at 1 less than or equal to x less than or equal to 3 rotating about the y-axis. Find the surface area of the sol...
