Answer:
6135.9m^3
Explanation:
V=3.14r^2 h/3
step by step
1. the radius is half so half of 25 is 12.5 that's the r in your equation
2.the height in your equation is 3 times more then the radius and your radius is 12.5X3 =37.5 for your height
3. plug everything in back into the equation v=3.14(12.5)^2(37.5/3)= 6135.923 when rounded it is 6135.9m^3
