The area of a circle is 2464 cm2. What is the diameter of this circle?[Use π = 22/7]
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 56 cm.
Area of a circle = π × Radius2
⇒ 2464 = {22/7} × Radius2
⇒ 784 = Radius2
Thus, Radius = 28 cm
Diameter = 2 × 28 = 56 cm
