Ms. Brown served her apple pie on a 21 inches radius dish. She wanted to tie a ribbon around the dish to make it a little more festive. How long does the ribbon need to be in order to fit the dish? Use 22/7 as π. (only enter the final 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

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
