Answer:-

  • volume of cylinder formed is 14148.75cm³

step-by-step explaination:-

Given:-

  • width of rectangular paper = 30cm.

  • length = 77cm

length of rectangle = circumference of circle of cylinder

and width of rectangle = height of cylinder

so ,

  • => 77 = 2πr

  • => 77 × 22/7 × 2 = r

  • 49/4 = r

now,

volume of cylinder = πr²h

=22/7 × 49/4 × 49/4 × 30

= 14148.75cm³
