If the radius of a cylinder was shrunk down to a quarter of its orignal size and the height was reduced to a third of its original
size, what would be the formula to find the modified surface area?

a² + b²= c²

24² + 7² = c²

c= 25

d is the answer

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
