The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.
Step-by-step explanation:
The cost of cooling 30000 cubic foot house = $7
Cost per cubic foot = 7/30000
=$0.00023
The cost of cooling 25000 cubic foot house= $6.50
Cost per cubic foot=6.50/25000
= $0.00026
The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.
In 1 second it beats about 53 times
In 5 seconds it will beat about (53/1*5) times
= 265 times
Answer:
207 cubic centimeters
Step-by-step explanation:
Given
volume of cone = 9 cubic centimeters
Since the cone and cylinder above have the same radius, r, and height, h, then r = h
volume of the cone = 1/3πr²h
69 = 1/3πr²h
πr²h = 69*3
πr²h = 207cubic cm
Since the volume of the cylinder = πr²h
Hence volume of the cylinder is 207 cubic centimeters
