Alright, so you can try to study hard and gain a passing grade (A+) for the other two quarters.
The answer is B. If you multiply it you get the original problem.
Step-by-step explanation:
step 1. the area of a circle is A. A = (pi)r^2.
step 2. if the diameter is 8 cm then the radius is 4 cm.
step 3. A = (pi)4^2
step 4. A = 16(pi) = 50.24 cm.
If you are trying to see how much the population is in 1800, it is 9.24 million. You add the population from 1790 and the amount it has grown for 1800.
2/3=0.66666666........
66%=66/100=0.66
so, 2/3 is bigger
