Step-by-step explanation:
Find the scale factor of the two cylinders:
Figure A has an r of 4 and figure B has an r of 2:
2 / 4 = 0.50, so Figure B is half the size of Figure A.
Since you want the volume, which is measured in cubic units, you need to cube the scale factor:
0.5^3 = 0.125
Multiply the volume of Figure A by the scale factor:
352 x 0.125 = 44 cubic feet.
Check the picture below.
bear in mind that, arcs get their angle measurement, from the central angle they're in.

Answer:
The amount Trevor's family pay per minute on shower water is $0.005.
Step-by-step explanation:
The cost of water is,
Cost = $0.20/liter
Amount of water used over the entire month:
Amount of water used = 72 liters
Compute the total water cost as follows:
Total water cost = Amount of water used × Cost
= 72 × 0.20
= $14.4/liter
The average number of minutes each person showered is:
Average number of minutes = 480 minutes.
The number of people in Trevor's house:
N = 6
Compute the total amount of time the 6 person showered as follows:
Total amount of time = Average number of minutes × N
= 480 × 6
= 2880 minutes
Compute the pay per minute on shower water as follows:
Pay per minute on water = Total water cost ÷ Total amount of time
= $14.4 ÷ 2880
= $0.005
Thus, the amount Trevor's family pay per minute on shower water is $0.005.
