Remember

so let's rewrite them
25=5^2
so




yep, that's definitely true
The next nearest hundred for this equation is 1,000 so the answer is 5,000.
I hope this helps ;)
The best way to justify which answers are correct are to calculate the circumference and the area for each of the circles with the given radii. I organized this information into a chart.
Circumference | Area
1/2 3.14 0.785
1 6.28 3.14
1 1/2 9.42 7.065
2 12.56 12.56
2 1/2 15.7 19.625
The first three choices will result in a numerical value for the radius that is smaller than the area.
Answer:
Step-by-step explanation:
(4 + x)/2 = 2
4 + x = 4
x = 0
(x + 0)/2 = 1.5
x + 0 = 3
x = 3
(0, 3)
answer is C
