The radius of a sphere is 6 cm which is the volume of the sphere

Mathematics
1 answer:
Margarita [4]3 years ago
8 0

Answer:

3 or C

Step-by-step explanation:

The volume of a sphere is denoted by: V = \frac{4}{3} \pi r^{3} , where r is the radius.

Here, r = 6, so we just plug in this value: V = \frac{4}{3} \pi (6^3)=\frac{4}{3} \pi *216=288\pi

So, the answer is 3 or C.

Hope this helps!

trasher [3.6K]

Differentiate the given solution:

y=\dfrac1{x^2+C}\implies y'=-\dfrac{2x}{(x^2+C)^2}

Substitute y and y' into the ODE:

-\dfrac{2x}{(x^2+C)^2}+2x\left(\dfrac1{x^2+C}\right)^2=0

and it's easy to see the left side indeed reduces to 0.

Ann paid $5.20 in sales tax for an $80 purchase. What percent sales tax
Doss [256]

Answer:

$22.84

Step-by-step explanation:

The tax is calculated by 0.075 * 21.25 = 1.59375 or $1.59. So the total bill is the cost of items purchased plus tax, which is $21.25 + $1.59 = $22.84.

PLEASSSEEEE HELLLLP MEEEE!
Vanyuwa [196]

Answer:

1) C = 3

2) B = 5

3) C = 8

Step-by-step explanation:

Question 1)

We have:

(2x+3)(4x-1)

Distribute:

=(2x+3)(4x)+(2x+3)(-1)

Distribute:

=8x^2+12x-2x-3

Combine like terms:

=8x^2+10x-(3)

Therefore, C = 3.

Question 2)

We have:

(x+2) (2x^2+x-1)

Distribute:

\displaystyle =(x+2)(2x^2)+(x+2)(x)+(x+2)( - 1)

Distribute:

=(2x^3+4x^2)+(x^2+2x)+(-x -2)

Combine like terms:

=2x^3+(5)x^2+x-2

Therefore, B = 5.

Question 3)

We have:

(x+2)(x^2-3x-2)

Distribute:

=(x+2)(x^2)+(x+2)(-3x)+(x+2)(-2)

Distribute:

=(x^3+2x^2)+(-3x^2-6x)+(-2x-4)

Combine like terms:

=x^3-x^2-(8)x-4

So, C = 8.
