Two parallel lines touch the circles at P and Q, The Area of the circle is 154 cm². Find the length of PQ (Take π = )
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 14 cm
Given that
Area of the circle = 154 cm²
Two parallel lines touch the circles at P and Q
Formula used
Area of circle = π × r2, where 'r' is the radius
Diameter = 2r
Calculation
⇒ π × r2 = 154
⇒ r = 7 cm
⇒ Diameter = 2 × 7 = 14 cm
Hence, the length of PQ is 14 cm
