Check Answer Please. Calculate capacity of a Reservoir.

Please check my answer. This is is for very important mark and I just need someone to double check the answer.

Question - Calculate the capacity of a reservoir ( cylinder shape) if it is full... The height is given as 3.5 meters. The diameter is given as 6.4meters.

My answer is 112.639. It this correct.

Thank you!!!!

I get 112.5946807 using the pi in my calculator, which is probably more accurate than 3.14159...
Do NOT forget to put "Cubic Metres".
Calculating backwards from your answer suggests that the value of pi which you used was 3.142829241. My calculator uses pi = 3.141592654.

Radius is 6.4/2 = 3.2
Volume is = 3.2 x 3.2 x 3.14 x 3.5 = 112.5376 m^3

you are right
