Question

can someone explain these sums have same question so why these solve by different methods.
sum 1- we take lenght as height and breadth = circumference of base
sum 2- we take lenght= circumference of base and breadth as height
why?????​​​

Answer 1

Step-by-step explanation:

the 1st sum is rolled from the side where the value is 22 (i.e., breadth)

so 2πr = 22

= 2 ×22/7 × r = 22

= 44/7 × r = 22

= r = (22 × 7)/44

= r = 7/2 = 3.5

& the 2nd sum is rolled from the side where the value is 44 (i.e., length)

so 2πr = 44

= 2 ×22/7 × r = 44

= 44/7 × r = 44

= r = 7

the circumference is from which side it's rolled,
