Find the volume of the solid generated when the region bounded by y=5 cos x and the x-axis on the interval [0,\frac{\pi }{2}] is revolved about the y-axis. (use the shell method)

care to share were the trapezoid shown is ?

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
