The tank is being filled with drinking water by using a bucket that can hold 0.34 cubic feet of water. emma is able to pour 5 full buckets into the tank every 3 minutes. how long will it take to fill the water tank completely at this constant rate? use 3.14 for pi and round to the nearest whole minute.

The formula for volume of a cylinder is V=r^2h, where V= volume, r=radius, and h=height. So we plug in your numbers and get (3.14)(1.5)^2(4), which equals 28.26 cubic feet. We have a bucket that holds 0.34 cubic feet, so we need to fill it 28.26/0.34 times, which equals about 83.118 times. If she can fill the bucket five times in three minutes, we set up a ratio 3/5 = 83.118/x so 5x=249.3529, and x=49.87 minutes.
