Hey!

------------------------------------------------

Slope Formula: m = \frac{y2 - y1}{x2 - x1}

------------------------------------------------

Solution:

m = \frac{y2 - y1}{x2 - x1} \\m = \frac{9 - 7}{-1 - 5}\\m = \frac{2}{-6} \\m = \frac{1}{-3}

What is the approximate volume of the cylinder? Use 3.14 for п.
Veseljchak [2.6K]

<u>Given</u>:

Given that the radius of the cylinder is 4 cm.

The height of the cylinder is 9 cm.

We need to determine the volume of the cylinder.

<u>Volume of the cylinder:</u>

The volume of the cylinder can be determined using the formula,

V=\pi r^2 h

where r is the radius and h is the height of the cylinder.

Substituting π = 3.14, r = 4 and h = 9 in the above formula, we get;

V=(3.14)(4)^2(9)

V=(3.14)(16)(9)

V=452.16 \ cm^3

Thus, the volume of the cylinder is 452.16 cm³

Hence, Option B is the correct answer.
