ASHA 777 [7]

Answer:

Rounded to the Nearest Tenth is V=769.3π

Step-by-step explanation:

The diameter of the figure is 7, so the radius is 3.5. So, the radius is 3.5

The height is 20

Formula for cylinders= V= Bh or V=πr2h

I will use V=πr2h

V=π(3.5)²(20)

V=π(12.25)(20)

V=π(245)

V=769.3π

Some more fractions, with common denominators

kenny6666 [7]

Answer:

$\frac{5}{6}-\frac{1}{9} = \frac{45}{54} -\frac{6}{54} = \frac{13}{18}$

Step-by-step explanation:

An easy way to find a common denominator is to multiply the denominators against each other, like this:

$(\frac{9}{9})\frac{5}{6}-\frac{1}{9} (\frac{6}{6})$

Now, simplify:

$\frac{45}{54}-\frac{6}{54}$

Then, subtract:

$\frac{39}{54}$

Simplify:

$\frac{13}{18}$ (Divide numerator and denominator by 3)

Hope this helps!!
