Answer:
The area of the new circle is 804.57 cm^2
Step-by-step explanation:
In this question, we are interested in calculating the area of the new circle of the radius of the old circle was doubled.
Let’s calculate the former radius first;
Mathematically;
Area of a circle = π * r^2
Thus;
201.06 = π * r^2
r^2 = 201.06/π
r^2 = 63.999
r = √63.99
r = 8 approximately
Now let’s double this radius and it becomes 2 * 8 = 16 cm
The new area will be ;
22/7 * 16 * 16 = 804.57 cm^2
