I think it would be 5/7 because it says that square B is 5/7 of square A.
Answer:
You will need to buy 5 1.50lb bags of sugar to make your recipe.
Step-by-step explanation:
This problem can be solved by consecutive rules of three.
A large recipe calls for 3.18kg of sugar. Your bags of sugar are measured in pounds (lb). Remembering that 1kg=2.20462lb
How many lbs of sugar you will need to buy?
1 kg - 2.20462lb
3.18 kg - x lb
How many 1.50lb bags of sugar will you need to buy to make your recipe?
1 bag - 1.50 lb
x bags - 7 lb
You will need to buy 5 1.50lb bags of sugar to make your recipe.
Square root 62.8. Which will give you 7.9.
7.9 divided by pi times 5.
7.9 divided by 15.7.
The radius would be 1.9 if left as a decimal, but rounded to the whole number would be 2.
Hope this helps and answers your problem!!!
