Question 1090008: will you please check my math?
Question is, How many cubic yards of concrete will it take to pour a cylindrical column 14 ft high with a diameter of 2 ft? Round to the nearest tenth.
v=3.14xr^2xh
3.14x1x14=43.96 cu ft
1 cu yd= 27 cu ft
43.96/27= 1.628
nearest tenth is 1.6 cu yd.
Please correct me if I am wrong
