The formula for the volume of a sphere is V=(4/3) (pi) r^3. if r is doubled then you get 2r as the radius and V=(4/3) (pi) * 8r^3 so the volume is eight times bigger than the original  r  value. if r is tripled the r =3r  and (3r)^3 so the volume is 27 times bigger. If r  is multiplied by  n  the radius is  nr  and (nr)^3 =n^3  r^3, Therefore, the volume is n^3 times bigger than the original.

astra-53 [7]

Answer:

$108

Step-by-step explanation:

You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.

I=Prt\\

<em>I = interest amount </em>

<em>P = principal amount </em>

<em>r = interest rate (decimal form) </em>

<em>t = time</em>

First, change 2% into its decimal form:

2% -> \frac{2}{100} -> 0.02

Next, plug in the values into the equation:

I=1,800(.02)(3)

I=108

Coach Cliffman earned $108 of interest after 3 years.
