Answer 2

Answer:

Answer:

$\huge\boxed{D.\ -5x-24}$

Step-by-step explanation:

$3(2x-8)-11x\qquad|\text{use the distributive property}\ a(b+c)=ab+ac\n\n=(3)(2x)+(3)(-8)-11x=6x-24-11x\qquad|\text{combine like terms}\n\n=(6x-11x)-24=-5x-24$

The spherical container has a radius of 21 cm. What is the approximate volume of the container?
Use 3.14 to approximate pi and express your answer in hundredths.

cm3

Answers

To solve this, we need the formula for the volume of a sphere. The formula is expressed as the 4/3 of the product of the cube of the radius and pi.
Volume = 4/3 (π x r^3)

Substituting the given values, we have:

Volume = 4/3 (3.14 x 21^3)
Volume = 38772.720 cm^3

Thus, the approximate volume of the container is 38772.720 cm^3.

Answer:because it’s a spherical container, and you’re looknng for the volume, the correct answer is 38772.720
