GCF (18,42) = 2*3 = 6
\dfrac{18}{42} =  \dfrac{18:6}{42:6} =  \dfrac{3}{7}

\frac{18}{42}=\frac{18:2}{42:2}=\frac{9}{21}=\frac{9:3}{21:3}=\boxed{\frac{3}{7}}

A can in the shape of a right circular cylinder is required to have a volume of 500 cubic centimeters. The top and bottom are ma
borishaifa [10]

Answer:

The answer to the question is

The total cost C of the material as a function of the radius r of the cylinder is

0.6912·r² + 800/r Dollars.

Step-by-step explanation:

To solve the question, we note that

The area of the top and bottom combined  = 2·π·r²

The area of the sides = 2·π·r·h

and the volume = πr²h = 500 cm²

Therefore height = 500/(πr²)

Substituting the value of h into the area of the side we have

Area of the side = 2πr·500/(πr²) = 1000/r

Therefore total area of can = Area of top + Area of bottom + Area of side

Whereby the cost of the can = 0.11×Area of top +0.11×Area of bottom +0.8×Area of side

Which is equal to

0.11×2×π×r²+ 0.8×1000/r = 0.6912·r² + 800/r

The cost of the can is $(0.6912·r² + 800/r)
