The Area of a circle is 4 pi in^2. What is the circumference, in inches? Express your answer in terms of pi.

Step-by-step explanation:

pi r 2 = 4 pi ^2

then r^2 =4pi

r =2√pi

now circumference of circle = 2pi r

= 2pi 2√pi

= 4 pi √pi

4pi ^2 by √pi

lo.lll

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
