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.
Assuming, it's decimal logarithm.

To satisfy his grandmother’s request, Dave must mix 3/5 cups of fruit for a single cup of nuts.
Answer:
125 is 80% of 156.25
Working out percentages
We have, 80% × x = 125
or,
<u>80
</u>
100
x = 125
Multiplying both sides by 100 and dividing both sides by 80,
we have x = 125 ×
<u>100
</u>
80
x = 156.25
If you are using a calculator, simply enter 125×100÷80, which will give you the answer.
Hope This Helps! Have A Nice Day!!
