40=6.95c+5.25
The $40 is what you want it all to equal, so that goes to one side by itself.
The CDs are 6.95 each, so they get a variable to show that.
The 5.95 is added to that, showing that it's only charged once.
Then, all you have to do is solve for c, which is the number of CD's you can buy.

The curved surface area of solid cylinder is  

 

As we are given that:

Diameter of solid cylinder = 8 cm

Length or Height o solid cylinder = 140 cm

Formula used to calculate the curved surface area of cylinder is:2n x h

Curved surface area of cylinder =2r x h  

where,

r = radius of cylinder

h = height or length of cylinder

Radius of cylinder =  daimeter

Now putting all the given values in above formula, we get:

Curved surface area of cylinder =  2x 22/7 x 140cm

Curved surface area of cylinder = 3520cm^{2}

Therefore, the curved surface area of solid cylinder is3520cm^{2}
