Step-by-step explanation:
- The equation of a circumference is
. - Then , in this case
, and then to know the value of r we just simply have to calculate the square root of 9, which is 3.
The volume is 12x20x10 then divide by 2
200x12=2400
2400/2= 1200
23/103 = 0.22
0.22*100 = 22%
The percentage increase is 22%
