Im pretty sure its 1.09375
Let us consider 48 as 100%
so,
48------------->100
x -------------->75
therefore,
100*x=48*75
x=(48*75)/100
x=36
Answer
Find out the volume of a cylinder .
To prove
Formula

Where r is the radius and h is the height.
As given
Diameter of 12 in. and a height of 7 in.


Radius = 6 in

put all the values in the formula

= 791.28 in³
Therefore the volume of the cylinder is 791 .28 in³ .
