Volume of a cylinder = the area of the base x height of the cylinder
Area of base =

r^2
A = 6^2(

)
A = 36

V = 36

x 12
V = 432

5 cylinders = 5V
5V = 5 x (432

)
5V = 2160

Final answer: Alex needs to buy 2160

or 6785.84 cubic feet worth of compressed air to fill all of the cylindrical tanks.
Answer:
9.4m is the answer.
Step-by-step explanation:
a = 8m
b = 5m
c = ?
According to the Pythagoras theorem,
a² + b² = c²
8² + 5² = c²
64 + 25 = c²
89 = c²
c = 9.433
Rounding off,
c = 9.4m
Circumference is Diameter * 3.14
so D * 3.14 = 31.4
31.4 / 3.14 = 10 so the diameter is 10.
the radius is half of the diameter so radius = 5 centimeters.
Answer:
x=3/4
Step-by-step explanation:
x/3=1/2^2
4x=3
4x/4=3/4
x=3/4
