7 0

Answer:

-56

Explanation:

From the equation:

0.75(x + 20) = 2 + 0.5(x - 2)

Open brackets

0.75x + 15 = 2 + 0.5x - 1

Collect like terms

0.75x - 0.5x = 2 - 1 - 15

0.25x = - 14

Divide both sides by 0.25

x = -56

Find the exact volume of this cylinder in terms of π. refer to your staar 8th grade math reference sheet for the appropriate for

lakkis [162]

The exact volume of this cylinder is equal to 225π cubic centimeters.

<h3>How to calculate the volume of a cylinder.</h3>

Mathematically, the volume of a cylinder is given by this formula:

$V = \pi r^2h$

<u>Where:</u>

h is the height.

r is the radius.

<u>Given the following data:</u>

Height of cylinder = 9 cm.

Diameter of cylinder = 10 cm.

Radius = $\frac{diameter}{2} =\frac{10}{2} =5\;cm$

Substituting the given parameters into the formula, we have;

$V = \pi \times 5^2 \times 9\\\\V = \pi \times 225$

Volume = $225\;cm^3$
