Answer: 9.5
Step-by-step explanation:
Diameter of the spherical storage tank = 24 ft
So, radius of the tank = 
ft
Volume of the spherical tank = 4/3 * PI * r³
= 
= 7234.56 cubic feet
Diameter of cylindrical tank = 4 ft
So, radius = 
ft
Height of cylindrical tank = 10 ft
Volume of cylindrical tank = PI * r² * h
= 
cubic feet
So, the number of cylindrical tanks that can be filled from the spherical tank are =
Hence, 57 cylindrical tanks can be completely filled from the big spherical tank.
Answer
W=7
Explanation:
The formula for the perimeter for a rectangle is P = 2L + 2W
The formula for the area of a rectangle is A = LW
where L = length and W = width
P = 22 and A = 28
22 = 2L + 2W
28 = LW
Rewriting the 2nd equation L = 28/W
Substituting this into the first equation
22=2(28/W) + 2W
Reworking the equation to eliminate the denominator
22W = 2(28) + 2W2
22W = 56 + 2W2
and
2W2 - 22W + 56 = 0
Dividing by 2
W2 - 11W + 28 = 0
(W-7)(W-4)
Set each factor equal to 0 and solve each for 0
W = 4, W = 7
then W = 4
