Answer:
50.24 sq. units
Step-by-step explanation:
S = 4πr² = 4×3.14× 2² = 3.14 × 16 = 50.24 sq. units
They both have to be above the x axis, which makes B incorrect. B will be below the x axis. If you have a graphing calculator or know where there is one of the net, you can try it.
A and D are both wrong. The 1/2 does not become 2. What will happen is that 2 will make the graph wider.
There's only 1 answer left and that is
C <<<<<===== answer.
C reflects right across the y axis.
It means it is asking for a large number so it can represent more of the population because the larger the number the more percent of population so the answer would be A
It's c because. 80 divided. by 2 equals 40 then add 27 that equals 67
