I will award a medal to whoever helps me on this question: find the area for each circle with a diameter of 11 ft???

OpenStudy (anonymous):

2pi*r is the equation for this, so to get r you divide the diameter in two. r = 5.5 feet so its 2pi*5.5 = 34.55 feet

OpenStudy (anonymous):

Some of my answers are 90ft , 95ft, 97ft, 99ft

OpenStudy (anonymous):

oh whoops I gave you the circumference not the area, so area is pi*r^2 so its 95.03 ft
