What is the area of a circle with a radius of 4 meters? Use 22/7 for pie .
Area of a circle is given by \(\pi r^2 \), where \( r\) is the radius. So, \(\frac {22}7 \times 4^2 = \frac{352}{7} \) sq mt
\( = 50.2857\) sq mt
@FoolForMath, do you guys use the abbreviation \(\text{mt}\) rather than \(\text{m}?\) In the states, it's always \(\text{m}.\) Just curious.
No we use 'm' typically but I have seen the usage of 'mt' :)
Interesting. You learn something new everyday. :P
