Question

a rectangle piece of a paper of length 35 cm and breadth 22 cm is rolled along the length of to form a cylinder find the radius of the base of the cylinder so formed​

Answer 1

Answer:

length of paper(L) =35 CM

breadth of paper (b) =22 CM

length of paper cylinder (h) =35 CM

To find:- radius of cylinder=?

solution:- when the paper is rolled along the length

Height of cylinder =22 cm

circumference of the base of the cylinder=35 cm

Let radius be the r cm

2πr= 35

2×22÷7 ×r = 35

r=35×7÷44

r=245÷44

r=5.5 cm

Ans :- radius is 5.5 cm
