DUE SOON PLEASE HELP A rancher has a cylindrical water tank that is 3 feet in radius and 8 feet high. How much water can the tank hold? Leave in terms of Pi.

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
