Answer:
The radius is 4.5, while the area is equaled to 63.585
Step-by-step explanation:
Formula of circumference: radius times 2 times pie (3.14)
Formula of Area of Circle: radius squared times pie (3.14)
Divide 28.26 by 2 and by pie (3.14) to get the radius. You should get 4.5.
Square 4.5 (the radius), which should equal to 20.25. Then, multiply it by pie (3.14), which is equaled to 63.585. This is the area of the circle.
