The area of a square is d. What is the area of the circle which has the diagonal of the square as its diameter?
Correct Answer: D
Question 3 Explanation:
In general,
Area of a square A = a2 (where a is side)
In the question,
Area of a square = d
The side of a square = √d
Diagonal of a square = Diameter of circle
From Pythagoras theorem,
Area of a square A = a2 (where a is side)
In the question,
Area of a square = d
The side of a square = √d
Diagonal of a square = Diameter of circle
From Pythagoras theorem,
πd
πd2
(1/2)πd2
(1/2)πd
