20% = 0.20
6 * 0.20 = 1.2
6 + 1.2 = 7.2
Circle B has a radius of 7.2.
Circle Area = pi *r^2
Lets use 3.14 for pi
3.14 * 7.2^2 = Area of circle B
7.2 * 7.2 = 51.84
3.14 * 51.84 = 162.7776
Area of circle B is 162.7776
Rounded to 2 decimals, this is 162.78
A. 189.31
D. 162.78
E. 203.15
are all equal to or grater than 162.78
Answer:
