<h2>
The volume of a cylinder (y) = 
</h2>
Step-by-step explanation:
Given by question,
The volume of a cylinder = y, The radius of a cylinder(r) = x - 3 and
The height of a cylinder(h) = 2x + 7
To find, the volume of a cylinder (y) = ?
We know that,
The volume of a cylinder = 
⇒ 
⇒ y = 
⇒ y = 
∴ The volume of a cylinder (y) = 
Thus, the volume of a cylinder (y) =

Let x be number of downloads of standard version and y be number of downloads of high quality versions.
The hight quality downloads are twice as the standar downloads. So,

The downloaded data for x standard version is 2.7x and for y high quality version is 4.2y. The total downloaded data is 3219. So,

Substitute 2x for y in the equation and solve the obtained equation for x.

So value of x is 290. Thus downloads of the standard version were 290.
Answer: 290
