Answer & Step-by-step explanation:
![Circumference=d\pi \\Area=r^2\pi](https://tex.z-dn.net/?f=Circumference%3Dd%5Cpi%20%5C%5CArea%3Dr%5E2%5Cpi)
The diameter of the circle is 8 m and the radius of the circle is 4 units. So, now we have to plug in the numbers so we can find the circumference and the area of the circle.
![Circumference=(8)\pi](https://tex.z-dn.net/?f=Circumference%3D%288%29%5Cpi)
![Circumference=25.12](https://tex.z-dn.net/?f=Circumference%3D25.12)
So, the circumference of the circle is 25.12 m.
![Area=(4)^2\pi](https://tex.z-dn.net/?f=Area%3D%284%29%5E2%5Cpi)
![Area=16\pi](https://tex.z-dn.net/?f=Area%3D16%5Cpi)
![Area=50.24](https://tex.z-dn.net/?f=Area%3D50.24)
So, the area of the circle is 50.24 units².
