Answer:

132 inch

Step-by-step explanation:

To find the length around the dish we need to find the perimeter

Perimeter of a circle = circumference = πd

Radius = 21 in

Diameter= 21x2 = 42 in

Therefore perimeter

= 22/7 x diameter

= 22/7 x 42

= 22 x 6

= 132 in

So, she will need a ribbon of length is 132 inches to tie around the dish
