In xy–plane, P and Q are two points having co– ordinates (2, 0) and (5, 4) respectively. Then the numerical value of the area of the circle with radius PQ is
Correct Answer: 25 π
Explanation:
According to question ,
PQ = √( 5 - 2 )2 + ( 4 - 0 )2
PQ = √9 + 16 = 5
∴ Area of circle = πr2
Area of circle = 25 π sq. units
