Question

Diameter of a cylindrical tank is 9 feet and the height of a tank is 25 feet. Find the approximate volume of the cylindrical tank to the nearest hundredth place

C. 1,589.63 cubic feet

D. 2,325.26 cubic feet

E. 6,358.50 cubic feet

F. 3,489.27 cubic feet.

Answer 1

The volume is 
.. V = π*r^2*h
.. = π*(4.5 ft)^2*(25 ft)
.. ≈ 1590.43 ft^3

The closest choice is C 1589.63 ft^3.

_____
Apparently, someone used the 3-digit approximation 3.14 for π to compute a 6-digit result. That is why it is wrong in the last 3 digits.
