I need to show work also

376.8 cubic centimeter of wax are needed for the candle.

Solution:

Radius of the cylinder = 2 cm

Height of the cylinder = 30 cm

The value of π = 3.14

To find how much wax are needed to make the candle:

Volume of the cylinder =

                                      = 3.14 × 2² × 30

Volume of the cylinder = 376.8 cubic centimeter

Hence 376.8 cubic centimeter of wax are needed for the candle.

what are the options? ?

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:
