Answer:
The radius of the can, rounded to the nearest hundredth, is 530.66.
Step-by-step explanation:
We want to do the reverse of the formula for <em>V</em>, which is pi(r)^2(h).
to isolate r.
Let's start by writing an equivalent equation to V = 
<em>h</em> by solving for r
Now, substitute and solve for r
1014 * 3.14 / 6 = 530.66
