A farmer has a water tank for cows in the shape of a cylinder with a radius of 7 ft and a height of 3 ft. The tank comes equippe
natima [27]

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

Use sigma notation to represent the sum of the first five terms of the following sequence. -5, -9.-13,
Delvig [45]

Answer:

\sum -5-9-13-17-21 =-65

Step-by-step explanation:

given nos -5,-9,-13,-17,-21

common difference=-4

given series are in arithmetic progression,

\sum -5-9-13-17-21=n\div 2\left \{ a+l \right \}

 where, n=5 , a=first term=-5 , l=last term=-21

\sum -5-9-13-17-21=5\div 2\left \{ -5-21\right \}

\sum -5-9-13-17-21 =5\div 2\left \{ -26\right \}

\sum -5-9-13-17-21 =-65     answer
