rightwards double arrow 88 equals space 2 space cross times space 22 over 7 cross times straight r
rightwards double arrow straight r space equals space 14 space cm
Diameter space equals space 2 straight r space equals space 2 cross times 14 space equals space 28 space cm
Area space of space straight a space circle space equals space πr squared space equals space 22 over 7 space cross times space 14 space cross times 14 space equals space 616 space cm squared
Area over 4 equals space 616 over 4 equals space 154 space
end style
