Answer 1

Answer:

long of ribbon =40.82 inch

Step-by-step explanation:

long of ribbon = 40.82 inch

here we find perimeter of a circle

there fore

perimeter of a circle =2πr

= 2×22/7×13/2

= 40.82

here π= 3.14

Answer 2

40.82 inch

Step-by-step explanation:

Length of Ribbon = Perimeter of Circle

》Perimeter of a Circle = ( below )

$2\pi \: r \\ 2x\frac{22}{7} x \frac{13}{2 } \\ 40.82 \\ (here \: x \: is \: multiplication \: sign)$

Its 2 × 22/7 x 13/2

( 2 Pi r - can also be 3.14 )

Hence , the answer is 40.82 inche
