You can put this solution on YOUR website! Pete consumed 9 cm^2 per bite and took a bite every 20 sec ___ he finished the pizza in 28 min
(9 cm^2 / bite)(3 bite / min)(28 min) = area of pizza consumed
pi * r^2 = area of circular pizza
plug in the area of the pizza , solve for r , multiply by 2 to find d
