Question

What is the area of a circle that has a circumference of pi?

Answer 1

do you know the formula for circumference of a circle? solve for the radius and plug that into the formula for the area of a circle.

Answer 2

area = pi r^2
circumference = 2 pi r
circumference = pi
pi / 2pi = r

area = pi(pi/2pi)^2

Answer 3

circumference=
\[2\Pi*r\]
so \[\Pi=2\Pi*r\]
r=1/2

Area =\[\Pi*r^2\]
but r=1/2
area=\[\Pi/4\]
