Answer
The volume is 98.3 x $10^{3}$ L or 9.83 x $10^{4}$ L
Work Step by Step
First we convert tank dimensions from feet to meter. Next calculate the volume in cubic meters and after that we convert cubic meters to liters.
Tank dimensions:
radius: 15.0 ft = 15.0 ft x $\frac{1 m}{3.3 ft}$ = 4.55 m
deep ( or height) 5.0 ft = 5 ft x $\frac{1 m}{3.3 ft}$ = 1.52 m
Tank volume:
V = π x $r^{2}$ x h
V = 3.14 x $(4.55 m)^{2}$ x 1.52 m
V = 98.3 $m^{3}$
Now convert 98.3 $m^{3}$ to L
98.3 $m^{3}$ = 98.3 $m^{3}$ x $\frac{10^{3}L}{1m^{3}}$
So the volume is 98.3 x $10^{3}$ L or 9.83 x $10^{4}$ L
