Answer:
A =
![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
Step-by-step explanation:
∵ The diameter of the mug is 8 cm and using to cut out circular cookies
∴ The diameter of each circular cookie is 8 cm
∴ Its radius = 8 ÷ 2 = 4
∵ Area of the circle = ![\pi r^{2}](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D)
∴ Area = ![\pi 4^{2}=16\pi cm^{2}](https://tex.z-dn.net/?f=%5Cpi%204%5E%7B2%7D%3D16%5Cpi%20cm%5E%7B2%7D)
The GCF is the largest number that can go into both the terms. Since "y" isn't in both terms, it can't include y. x, however, is, so we know our GCF has x in it. What's the largest whole number that can go into 32 and 18? 2. Your GCF is <span>2x.
