Find the volume of a cone that has a radius of 5 centimeters and a height of 7 centimeters.
Volume = cm³
(Use 3.14 for pi and round your answer to the nearest hundredth.)

Volume of the cone is 200 cm³

Step-by-step explanation:

Volume = 1/3 × 3.14 × 5² × 7

             = 183.17 in³ ≈ 200 cm³ (rounding off to nearest hundredth)

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:
