I'll mark the correct and well explained answer brainliest! find the volume of firgure a.

1375 cubic units.          

Step-by-step explanation:

Let , and be radius, height and volume of our large cylinder respectively. Let , and be radius, height and volume of our small cylinder respectively.

We have been given that both our given cylinders in graph are similar, therefore, the ratios between their radius, height and volume will be same.

We can also represent this relation as:

Since corresponding sides of similar figures are always in the same proportion, so the proportion between volume of our cylinders also will be same.    

Upon cancelling out pi from numerator and denominator we will get,     

Upon using the relation   in volume proportion we will get,  

Upon substituting our given values in this proportion we will get,      

Therefore, the volume of large cylinder will be 1375 cubic units.

your answer is a

step-by-step explanation:

4*4*4*4=256

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
