Answer 1

Answer:

it would be 8ft 6ft and 50%

Step-by-step explanation:

Answer 2

The volume of the tank be when the sensor turns on is 92.316 ft³

Calculation:

The volume of a cylinder is

= πr²h

= 3.14 × 7² × 3

= 3.14 × 49 × 3

= 461.58 ft³

Now the volume of the tank should be

= 20% of Volume of a cylinder

= 0.20 ( 461.58 ft³)

= 92.316 ft³
