Me ! can someone check my work? plz tell me if i did something

The problem is tricky because it actually gives you the diameter, not the radius. To get the radius, we need to divide 34 by 2 to get 17. Then we proceed as you did to get V = 24,501.42 m^3. Also notice that because we are working with volume, we have cubic meters, not square meters. Other than that, your answer was perfect!
