The formula for the volume of a sphere is the following:

V= \dfrac{4}{3} \pi r^3

Plug in V=5000π and solve for the radius.

5000 \pi = \dfrac{4}{3} \pi r^3

Divide both sides by \pi

5000 = \dfrac{4}{3} r^3

Multiply both sides by 3/4 (to eliminate the 4/3 on the right side)
Also, flip the equation so we have the unknown variable on the left side (math etiquette).

r^3=3750

Take the cube root of both sides

r \approx 15.5

Now, calculate the surface area since now we know the radius.
The formula for the surface area is the following:

S=4 \pi r^2

Plug in r=15.5

S \approx 3033

The second choice is your answer.

Answer:

\frac{31x-159}{168y}

Step-by-step explanation:

\frac{x-4}{7y} - \frac{x+7}{8y} + \frac{x+3}{6y}

the LCD of the denominators is 168y , then

\frac{24(x-4)-21(x+7)+28(x+3)}{168y} ← distribute and simplify numerator

= \frac{24x-96-21y-147+28x+84}{168y}

= \frac{31x-159}{168y}

I have 30 coins consisting of nickels, dimes and quarters. The total value of the coins is $4.60. there are two more dimes than
aleksklad [387]

If you have 1 nickle, how many quarters do you have? (3)

If you have 4 nickles, you have 3 times as many quarters (3)(4) = 12

If you have n nickles, then you have 3n quarters so 3n = q, you have  a slightly different equation.

 

If you fix this equation and use substitution like you did, you can get the right answer; you can also try to work in the other information that you have - converting all coin values to cents

    5n + 10d + 25q = 460
