The water inside a right cylinder tank is 6 inches above the bottom part of the tank of radius 1 feet and length 2 feet. Find th

ASHA 777 [7]

Answer:

Step-by-step explanation:

Volume of the water is equivalent to the volume of a cylinder = πr²h where;

r is the radius of the cylindrical tank

h is the height of the water

Given parameters

radius of the cylindrical tank r = 1feet = 12 inches

height of the water inside the tank = 6inches

Volume of the water = πr²h

Volume of the water = π(12)²*6

Volume of the water = π*144*6

Volume of the water = 864π in³

<em>Hence the volume of the water is 864π in³</em>

Jack's last six scores are 75,78,83,80,79,84. If he scores a 90 on the next test, by how much will his mean test score increase?

kondaur [170]

Answer:

1.46

Step-by-step explanation:

First find the the mean score before he made a 90.

$\frac{75+78+83+80+79+84}{6} = 79.83$

Now add the score of 90 and calculate.

$\frac{75+78+83+80+79+84+ 90}{7} = 81.29$

Subtract the two scores.

$81.29-79.83 = 1.46$

His mean test score increased by 1.46.
