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

For the following right triangle, find the side length of x. round your answer to the nearest hundredth.
tatyana61 [14]

Answer:

14.87 units

Step-by-step explanation:

The sides of all right triangles share the same relationship known as the Pythagorean Theorem a² + b² = c². Substitute the lengths of the triangle into the theorem and solve for the unknown side. Since the problem does have an attached a picture, assume that a = 10, b = 11, and c = x.

10² + 11² = x²

100 + 121 = 221²

221 = x²

√221 = √x²

14.87 = x
