Question

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.

Answer 1

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
