Given,

Cylinder A has a volume of 6 cubic units

and height =3 units

The radius of cylinder A,

$\begin{gathered} r=\sqrt[]{\frac{V}{\pi h}} \\ =\sqrt[]{\frac{6}{3\pi}} \\ =0.8 \end{gathered}$

To find the volume of a cylinder B

$\begin{gathered} V=\pi r^2h \\ =(3.14)\times(0.8)^2\times(3) \\ =6.03 \end{gathered}$

Thus the volume of cylinder B is 6.03

What is 7/2 divided by 49/4?

ruslelena [56]

Answer:

$\frac{2}{7}$

Step-by-step explanation:

$\frac{7}{2}$ ÷ $\frac{49}{4}$ needs to be flipped and multiplied.

It will become $\frac{7}{2}$ · $\frac{4}{49}$ .

Simplify the fractions by replacing 7 with 1 and 49 with 7, since 7 is 1/7 of 49. Then, turn the 2 into a 1 and the 4 into a 2, since 2 is half of 4.

You will be left with 1 · $\frac{2}{7}$ , which equals $\frac{2}{7}$
