The formula for the area of a circle is 4 3 \frac{4}{3} X π X r 3 r^{3}

If you take π = 3.14 then your answer will be 1436.02666....

but,

If you take π = 22 7 \frac{22}{7} , then your answer will be 1437.333...

But both the answers are correct, so don't worry!

4 3 × π × 7 3 = 1436.76 \frac{4}{3} \times \pi \times 7^{3} = 1436.76

NOTE: π = 3.141592654 \pi = 3.141592654
