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
5. 14 squared centimeters
6. 31 7/8 squared inches
7. 936 squared inches
8. 125 squared centimeters
9. 72 squared meters
10. 336 squared meters
11. 8.25 squared feet
12. 187.5 squared inches
13. 1,620 squared inches
14. 300 squared feet; trapezoid's equation was (10+18)6/2. For the rectangle, equation was 18x12. Add the answers together to get 300.
I hope this helped! :)
1) L×W 12×12=144
2) 12+12+12+12=48
3) L×W×H 5×5×5= 125
5) B×h/2 12×9=108/2=54
