Recallin that, the diameter is twice as long as the radius, namely the radius is half the diameter, so, if the diameter is doubled, the radius is also doubled.
notice, the new volume is 4 times (πr² h), namely 4 times the original.
Answer:
Hmm, remember to use distributive property with the fraction and the numbers in the parenthesis.

Answer:
The butterfly travels 660 ft in 1.25 min.
Step-by-step explanation:
If the distance, d, a butterfly flies varies directly as the time,t in the air, then we can write the mathematical statement.
If we introduce the constant of proportionality, we obtain;
According to the question, when 
, 
.
We substitute these values to obtain;
The direct variation equation now becomes
When 
Therefore the butterfly will travel 660 ft in 1.25 min.
