Answer:
volume of the tank be when the sensor turns on = 92.316 ft³
Step-by-step explanation:
Volume of a cylinder = πr²h
Pi = π = 3.14
Radius = r = 7 ft
Height = h = 3 ft
Volume of a cylinder = πr²h
= 3.14 × 7² × 3
= 3.14 × 49 × 3
= 461.58 ft³
The tank comes equipped with a sensor to alert the farmer to fill it up when the water falls to 20% capacity.
volume of the tank be when the sensor turns on = 20% of Volume of a cylinder
= 0.20 * 461.58 ft³
= 92.316 ft³
volume of the tank be when the sensor turns on = 92.316 ft³
Answer: 24.7

Answer:
Using mental math, the approximate tip to leave for a bill of $81.79, if you tip 15% would be?
c.$12.30
Step-by-step explanation:
10% is $8.179, then 5% is a half of this sum, i.e. $8.179:2=$4.0895
3. 15%=10%+5% and in $ it is $8.179+$4.0895=$12.2685 that is nearly $12.30.
