Answers
Correct Question :- Find the area of the shaded part, if the side of the square is 8 cm and the circumference of circle is 44 cm ?
Solution :-
we know that,
- circumference of the circle = 2πr .
- Area of circle = πr² .
- Area of square = (side)²
given that,
→ circumference of the circle = 44 cm.
→ 2 * (22/7) * r = 44
→ (44/7) * r = 44
→ r = 7 cm.
then,
→ Shaded Area = Area of circle - Area of square
→ Shaded Area = (πr²) - (side)²
→ Shaded Area = (22/7 * 7 * 7) - (8)²
→ Shaded Area = 154 - 64
→ Shaded Area = 90 cm². (Ans.)
