Asatellite launch rocket has a cylindrical fuel tank. the fuel tank can hold v cubic meters of fuel. if the tank measures d meters across, what is the height of the tank in meters?

The volume of a cylinder with flat ends is (pi) x (radius squared) x (length) .

Radius of the tank = 1/2 diameter = d/2.

Volume = (pi) x (d/2)² x (height)

Height = ( V ) / ( pi  x  d²/4 )

Height =  ( 4V ) / ( pi d² )

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance
