A cylindrical water tower has a height of 6 ft and a radius of 4 ft. How much water does the tower contain when it is \(\frac{1}{3}\) full? Approximate \(\pi\) as 3.14. Round your answer to the nearest tenth.

A. 301.4 cubic feet
B. 75.4 cubic feet
C. 100.5 cubic feet
D. 150.7 cubic feet

Answer :

V = pi r^2 h
But it says 1/3 full so
1/3 pi r^2 h
1/3 * 3.14 * 4^2 * 6
100.48ft cubed
Whichrounds off to 100.5
