The volume of cylinder is 448 pie cm cube and height 7 cm find its radius

Verizon [17]

Answer:

$r =\bf 8 \space\ cm$

Step-by-step explanation:

The formula for volume of a cylinder is as follows:

$\boxed{Volume = \pi r^2 h}$

where:

• r = radius (? cm)

• h = height (7 cm).

Substituting the values into the formula:
$448 \pi = \pi \times r^2 \times 7$

Now solve for $r$ :

⇒ $r^2 = \frac{448 \pi }{\pi \times 7}$

⇒ $r = \sqrt{64}$

⇒ $r =\bf 8 \space\ cm$

Two groups of students were asked how far they lived from their school. The table below shows the distances in miles:

pychu [463]

Answer:

C. The value for Group A is double the value for Group B

Step-by-step explanation:

First, you add all the numbers from each group.

A: The distance in total is 39.06

B: The distance in total is 19.53

To find the mean, which is another way of saying the average, you divide the sum with how many numbers there are. (hope this makes sense, I suck at wording)

A: There are 9 numbers in total, hence, 39.06/9 = 4.34

B: There are 9 numbers in total, hence, 19.53/9 = 2.17

Those are the mean distance for the two groups.

2.17 * 2 = 4.34

Hence, C (third statement)
