TRY THIS
AREA OF OUTER CIRCLE - AREA OF INNER CIRCLE = AREA OF SHADED PART.
FIND THE RADIUS OF OUT CIRCLE USING CIRCUMFERENCE FORMULA, i.e., 2πr
THEN FIND THE AREA OF OUTER CIRCLE.
AFTER THAT YOU SUBTRACT THE WIDTH OF THE PATH FROM THE OUTER RADIUS. AND THEN FIND THE INNER AREA USING THE FORMULA(πr²). AND THEN SUBTRACT THIS FROM THE OUTER AREA AND THE ANSWER WILL BE THE AREA OF THE SHADED PART.
