How do I find the volume of a solid by rotating the region bounded by the given curves about a specified line?

Step-by-step explanation:

if a region is bounded by two curves y=f(x) and y=g(x) on an internal a,b where 0<g(x)< f(x) then the volume of the solid obtained by the rotating region about the Y-axis is expressed by the integral of the difference of two functions: v= 2πbfax(x)jdx

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
