Find the volume of a right circular cone that has a height of 5.7 ft and a base with a
radius of 15.6 ft. round your answer to the nearest tenth of a cubic foot.

56652.3 ft^3

Step-by-step explanation:

The formula for the volume of a right circular cone is V=13pi*r^2*h where r is the radius of the base.

So V=13pi*(15.6)^2*(5.7)=56652.3

inequality:

620-37.4p ≥ 450

the minimum amount of packages needed to be removed from the elevator is 5.

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
