Question

If a circle has a circumference of C, what is the area of the circle in terms of C?

A=πC

A=C24π

A=2Cπ

A=2C2

Answer 1

@dakid88 @corig

Answer 2

radius is:
\[r=\frac{ C }{ 2 \pi }\]
then area A, is:
\[area=\pi*r ^{2}=\pi*\frac{ C ^{2} }{ 4*\pi ^{2} }=\frac{ C ^{2} }{ 4*\pi }\]

Answer 3

c=2 pi r
area pi r^2
sp area = c r /2

Answer 4

@dakid88 so would it be B

Answer 5

yes

Answer 6

thanks bro @dakid88
