Find the volume of the figure. Round to the nearest hundredth when necessary. I got 257.2288 I if this is correct, I am not sure how to round it to the nearest hundredth. or if to leave it this way.

ok
Volume of a cylinder = Area of the base x height
= pi*r^2 * h
= 3.14* 3.2^2*8
= 3.14*10.24*8
= 257.23 km^3
We got the same result, you just need to round to the nearest hundred.
pi = 3.14
r = 3.2 km
h = 8 km
