Answer:
The total cost of the cylindrical tank is $226.28
Step-by-step explanation:
Dimensions of the tank are: radius = 3 ft , height = 2 ft
Cost per cubic foot = $4
Now, total volume of the cylindrical tank =
Here, take π = 22/7
So, Volume =
So, the <u>volume of the tank = 56.57 cubic feet. </u>
Now, cost per cubic foot = $4
Hence, the total cost of the tank = Total Volume of the tank x cost per foot
= 56.57 x 4 = $226.28
So, the total cost of the cylindrical tank is $226.28
Meet in 2 hours
means that the distance covered over 2 hours adds to total distance which is 13miles
basically, imagine instead of moving in oposite directions, toward each other, imagine that one moves for 2 hours then theh other one moves for another 2 hours, total 13 miles
so
speed1=x
speed2=y
x is 2.1 more than y
x=2.1+y
distance=speed times time
time=2hours
speed=x and y
total distance=13
13=2x+2y
x=2.1+y
sub
13=2(2.1+y)+2y
13=4.2+2y+2y
13=4.2+4y
minus 4.2 from both sides
8.8=4y
divide both sides by 4
2.2=y
sub
x=2.1+y
x=2.1+2.2
x=4.3
