Answer:
Circumference: 43.9822971503 or 43.98
Area: 153.9380400259 or 153.94
Step-by-step explanation:
So basically for the circumference you use C= d×π which means that the circumference is equal to the diameter (radius times 2) multiplied by pi! For the area you use the formula A= r^2×π which means the radius squared (radius times itself) multiplied by pi! By the way you can also round pi down to 3.14 to make it easier. Anyway I hope this helps!!
