Answer:
37.68cm of ribbon
Step-by-step explanation:
This question is asking you to find the circumference of the two lids. To find circumference all you have to do is multiply the diameter (the radius times 2) by pi.
If the radius is 3 then the diameter of the lid is 6 because of 2*3=6. Now all you hade to do is multiply 6 and 3.14.
6*3.14=18.84.
This is the amount of ribbon you need for just one of the jars but you have a second jar so you would need to multiply this by 2 to get the total amount needed.
18.84*2=37.68
Its already written as a decimal but it can be 8 1/2
What do you need help with? it helps us to know the question!
4 x+9=13 X=4 subtract 9 from the 9 and 13 and 13-9 =4 so x=4
12+14+16=42, an even number
