Answer:

The area of a circle can be calculated by using the formula:

A = πr²

Step-by-step explanation:

I'm assuming that you are asking about how to calculate the area of a circle, so this formula would be it, where the symbol 'π' is pi, a number which never ends, but in calculations is typically rounded to 3.14. However, on your calculator you may have a button which you can press to find the area of a circle that way.

5 minutes.

Step-by-step explanation:

It is given that, Amelia can wash 8 plates in 24 minutes.

So, if this rate remains constant then 1 plate will be washed in $\frac{24}{8} = 3$ minutes.

Again, it is given that, Amelia bakes 12 cookies in 60 minutes.

So, if this rate also remains constant then she will bake 1 cookie in $\frac{60}{12} = 5$ minutes. ( Answer )
