The radius of a circle is 14 m. The area of the circle is:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 616 m2
The area of a circle of radius \(r\) is \(\pi r^{2}\); with \(\pi=\frac{22}{7}\), a radius that is a multiple of 7 makes the working short, because the 7 in the denominator cancels.
Putting \(r=14\) into \(\pi r^{2}\): \(\displaystyle\frac{22}{7}\times14\times14\)
\(22\times2\times14=616\), so the area is 616 m2
