Answer:

No, the ribbon would not be long enough to go around the edge of the cake.

Circumference ≈ 81.7 cm

Explanation:

1) Calculate the circumference of the cake

Circumference - the length around a circle

$C=2\pi r$ where r is the radius

Plug 13 in as the radius

$C=2\pi (13)\\C=26\pi\\C= 81.7$

Therefore, the circumference of the cake is approximately 81.7 cm.

Because the ribbon is only 36 cm long, it would not be enough to go around the edge of the cake.

I hope this helps!
