The volume of a can varies jointly as the height of the can and the square of the radius. A can with an 8 inch height and 4 inch radius has a volume of 402.12 inches cubed. What is the volume of a can that has a 2 inch radius and a 10 inch height

Therefore the volume of the can is 1256.625 inches cubes.

Step-by-step explanation:

The volume of can directly proportional to the height of the can and the square of the radius.

V= The volume of the can

h= Height of the can

r= radius of the can.

Here 402.12 inches cubes, 8 inch, 4 inch, 10 inch, 2 inch,

inches cubes

Therefore the volume of the can that has 2 inch radius and 10 inch height is 1256.625 inches cubes.

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:
