A closed cylindrical tank contains 36pi cubic feet of water and is filled to half its capacity. When the tank is placed upright
pentagon [3]

Answer:

2.12 ft above ground level

Step-by-step explanation:

Volume of the cylindrical tank is 36*π

Tank is filled to half its capacity, that means tank is filled 18*π, and level of water is 4 feet, then the height of the cylinder is 8 feet

With the above information we can calculate the radius of the base of the cylinder, according to

V  =  36*π  = π*r²*h     ⇒  36 = r²*h     ⇒   36/8 = r²    ⇒  r = 2.12 ft

Then the radius of the base is  2.12 ft

When the cylindrical tank is place on its side, the level of water inside have to be 2.12 ft above ground level. That is the level of half its capacity

Triangle MNP is transformed according to the rule T(4,–1). What is the y-coordinate of M”?
koban [17]
T(4,-1) means move 4 units to the right and 1 unit down.

Based on the image, M(-3,4) ; N(-2,1) ; P(-4,2)

So,
M:
-3 move 4 units to the right becomes 1 
4 move 1 unit down becomes 3
M'(1,3)

N
-2 move 4 units to the right becomes 2
1 move 1 unit down becomes 0
N"(2,0)

P
-4 move 4 units to the right becomes 0
2 move 1 unit down becomes 1
P''(0,1)
