Mathematics
1 answer:
Georgia [21]3 years ago

\frac{5}{7r}-\frac{2}{7r}

You have two fractions with the same (common) denominator, so you subtract the numerators and put that over the common denominator.

\frac{5}{7r}-\frac{2}{7r}=\frac{5-2}{7r}=\frac{3}{7r}

The volume of a cylinder is 8177 cm³. If the radius is 3 cm, what is the height
Virty [35]

Answer:

None of the options are correct

О E. 289.2 cm

Step-by-step explanation:

Volume of a cylinder = v = л r² h

л = 3.1416     (aprox)

r = radius

h = height

8177 = 3.1416 * 3² * h

8177 = 3.1416 * 9 * h

8177 = 28.2744 * h

8177/282744 = h

h = 289.2 cm
