There are 54 people on a city bus. The ratio of adults to children is 5 : 1. At the next stop 9 adults get off the bus. What is the new equivalent ratio of adults to children on the bus?

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
