Step-by-step explanation:
(a) use surface area formula of cylinder that is for Lateral surface area and for total surface area
LSA= 2πrh
TSA= 2πr(h+r)
(b) volume of cylinder= πr^2h
..........
B = √(13²-7²) = √(169-49) = √120
Answer:

Step-by-step explanation:
If Bradley makes less than $8 per hour.
Let Bradley's hourly rate = h
Therefore, an inequality to represent the real-world problem is:

- The variable in the inequality represents <u>Bradley's hourly rate</u>
- The inequality symbol needed is <u>Less Than</u>
- The constant is <u>8</u>
- The inequality that correctly represents the problem is:

Answer:
a) 9:11 am
b) 77°F
Step-by-step explanation:
a) From the clock shown in the image attached, we can see that the time that the sprinkler system is switched off is at 11:56 am. Since the strawberries are watered for a total of 2 hours and 45 minutes every day, the time that the sprinkler is switched on can be gotten by subtracting 2 hours 45 minutes from 11:56 am. Hence:
Time sprinkler system is switched on = 11:56 am - 2 hours 45 minutes = 9:11 am
b) Temperature in °Farenheit = (1.8 * temperature in degree Celsius) + 32°
Temperature in °Farenheit = (1.8 * 25°) + 32° = 45° + 32°
Temperature in °Farenheit = 77°F
