Question

Rectangular piece of paper, having 10 m breadth and 132 m length is rolled along its length to form a cylinder . What is the radius and total surface area
of cylinder?​

Answer 1

Step-by-step explanation:

b=10m,l=132m

2*pie*r=10

r=10*7/2*22

r=70/44

r=1.59m

TSA=2*pie*r*r+2*pie*r*h

=2*22/7*70/44*70/44+2*22/7*70/44*132

=1198.13m square
