Find the difference in the volume and total area of a cylinder with both a radius and height of1 r-1, h-1

Respuesta :

CEViktor04

Although I am not clear as to whether the radius is r—1 or otherwise, but if i work with the values i see then:

Volume — T. S. A.

= πr²h — (2πr²+2πrh)

So after the simplification, I substitute the values given,

r= r—1 and h=h—1

And the answer is...

π(r—1)(rh—3r—3h+5)!
