The area of a circle is 616 sq.m. Find its diameter? (π = 22/7)
1). 7 m
2). 14 m
3). 28 m
4). 56 m
This Question has 1 answers.
As per the given data,
Area of the circle = π × r2
Where, r = radius of circle
Area of the circle = 616 sq.m
⇒ π × r2 = 616
⇒ r2 = 616/π = 196
⇒ r = √196 = 14
∴ Diameter = 2r = 2 × 14 = 28 m
