What is the volume of a sphere if it has a radius of 3 feet? (use 3.14 for π.) 37.68 ft 3 904.32 ft 3 75.36 ft 3 113.04 ft 3

The answer is 113.04. Volume of a sphere is 4/3*pi*r³so 4/3*3.14*3³=113.04

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
