A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.
Col. A: \(Ď€r^2\)
Col. B: \(2Ď€r\)
Dividing both sides by \(Ď€r\);
Col. A: \(r\)
Col. B: \(2\)
OP = OQ = radius (r)
Therefore, POQ is an equilateral triangle with area \(4\sqrt{3}\)
i.e. Area of eq. triangle = \(\frac{\sqrt{3}}{4}r^2 = 4\sqrt{3}\)
\(r = 4\)
Col. A: \(4\)
Col. B: \(2\)
Hence, option A

triangle given is equilateral triangle ( angle given 60).
area of equilateral triangle =4root3
side of equilateral triangle=radius of circle=4
area of circle= 16pi
circumference of circle=8pi
hence quantity A greater than quantity B
answer A
area of equilateral triangle =4root3
side of equilateral triangle=radius of circle=4
area of circle= 16pi
circumference of circle=8pi
hence quantity A greater than quantity B
answer A
